Halo Landfall

Here’s a little bit of nostalgia to start off your week. Remember this? For years, I thought it was either bootleg footage or a fan project. The only video I could find of it was on some kid’s YouTube channel at 144p. But no, it’s official Bungie. Here it is in HD.

Z is for Zenith

pioneer_book_scifiHas space opera passed its zenith?

Sometimes, it certainly looks that way.  All the major stuff seems to be reprints of past series and reboots of decades-old franchises.  Star Trek, Star Wars, Stargate, Battlestar Galactica, Ender’s Game, Dune, Babylon 5–all the big names seem to have had their start at least a generation ago.  At any science fiction convention, you’re likely to see more gray-haired men than kids in their teens and twenties.  And if you go to a publishing conference, new adult, urban fantasy, and paranormal romance are ascendant.

I’ve noticed that people are using the term “science fiction” increasingly to describe stories that don’t have anything to do with space.  Dystopian, post-apocalyptic, steampunk, even time travel–all of these subgenres are certainly part of the fold, but they’re very different from the stories about starships and alien worlds.  And then you have all the markets for short fiction that have been forced out of business–and even a few larger publishers, like Night Shade Books which is now selling off all its assets (read: authors) to avoid bankruptcy.

I remember going to World Fantasy 2010 in Columbus, Ohio, and feeling dismayed at the complete lack of science fiction.  World Fantasy is (or was, at least) the premier professional conference for speculative fiction literature, but all of the attention was going to urban fantasy and steampunk.  On the freebie table where publishers often dumped ARCs and review copies of their books, the only space opera stuff I really saw were a couple of titles by Glen Cook and one other guy–and I watched that table hawkishly for the full three days of the conference.

Sometimes, it seems as if it would be so much better if I had grown up in the 80s.  That’s when science fiction really had its heyday.  But all through the 90s, the genre seems to have been on the decline, much like NASA and the US space program.

So is space-centered science fiction on the way out?  Have we passed the glory days, and it’s now just a long decline until it becomes an obscure niche, beloved by some, but enigmatic to others?

In spite of everything I said above, I actually don’t think so.  In fact, I think we’re on the cusp of a science fiction renaissance, and that sci-fi geeks like myself will look back twenty years from now and wish that they were born in our era.  Here’s why:

1) Scientific discoveries are transforming the way we see the universe.

The day I posted P is for Planets, NASA’s Kepler mission announced the discovery of three Earth-like worlds orbiting in the habitable zones of their stars.  The existence of alien Earths is not conjecture–it’s a confirmed fact.  As our ability to study these worlds improves, it’s only a matter of time, IMO, before we find a world that has life.

We’ve discovered the Higgs-Boson.  We’re unraveling the fundamental building blocks of the universe.  We’ve built telescopes to look back to the dawn of time itself, and we’re learning more about the cosmology of the universe every year.  Perhaps even more remarkably, we understand now how little it is that we actually know–that the entirety of the observable universe is only about 5% of it, and even that’s optimistic.

All of this will take time to trickle down to the popular consciousness, but with all the new discoveries that are happening, I think that’s already in the process of happening.  In particular, I think the recent discoveries in the realm of exoplanets and astrobiology are going to shake things up in a major way in the next five or ten years.

2) The privatization of space travel is paving the way for a rapid expansion into space.

The US space program has been plagued with funding problems since at least the end of the Cold War space race.  Since the space shuttle program was retired just last year, the only way for our astronauts to get into space is through the Russian Soyuz spacecraft at Baikonur.  If NASA had to put a man on the moon, they do not currently have the knowledge or technology necessary to do it.

In the private sector, though, it’s been a very different story.  SpaceX has had a number of successful launches recently, most notably sending the first unmanned resupply capsule up to the International Space Station.  And just a couple days ago, Virgin Galactic had the first successful test flight of its rocket-powered spacecraft.

It’s sad to see the space shuttle go, but there are a lot of reasons why the program was flawed and inefficient to begin with.  By handing things off to the private sector and turning space exploration into a viable business venture, we can hopefully overcome those inefficiencies and eventually make space accessible to the general public.

And then you have the organizations like Mars One that are looking even further ahead to the colonization of Mars.  There’s a groundswell of excitement for Martian colonization that is starting to get some real money behind it.  Will it go anywhere?  It’s hard to say right now, but even if it suffers another decade or two of setbacks, it’s getting public attention, especially from the younger generation.

3) Video games are bringing a fresh new look and feel to the genre.

Not all of the big sci-fi series hail from 70s and 80s.  Halo started up as recently as 2001, and it’s a multi-billion dollar franchise with games, books–even Legos.  In fact, there are lots of sci-fi video game franchises right now, many of them right on par with other classic space opera.  Just look at Starcraft, for example, or Mass Effect, or Eve Online and Sins of a Solar Empire.  The number of sci-fi games has been exploding.

In fact, this explosion has been happening for some time.  While literary science fiction may have suffered something of a decline back in the 90s, that was the heyday of games like Master of Orion and Sid Meier’s Alpha Centauri.  Flight simulators like Flight Commander and X-wing proliferated like crazy, while even some of the classic RPGs like Final Fantasy borrowed heavily from science fiction tropes.  And those are just a few of the games that I can list off the top of my head!

Whether or not literary sf is on the decline, a whole new generation has been introduced to the genre through the medium of video gaming.  This is not just a small niche audience playing this stuff, either–in the US at least, Halo is as mainstream as Monopoly or Settlers of Catan.  In fact, you could say that science fiction is more mainstream now than it ever has been, and a lot of that is due to sci-fi video games.

4) The e-publishing golden age is giving us thousands of new voices.

But what about the world of literary sf?  Are we in a decline?  Do people just not read science fiction anymore?  How bright is the future for science fiction literature?

Actually, this is the area where I’m the most optimistic of all.

The publishing industry is changing at the speed of light, much in the same way that the music industry changed about a decade ago.  Just as the MP3 revolution allowed all sorts of eclectic yet entrepreneurial artists to thrive without the oversight of record labels, the epublishing revolution is opening all sorts of doors for the enterprising author.  And while the changes are driving publishers (such as NSB) out of business, they are enabling authors who only sell in the mid-list range to make a respectable living.

At Worldcon 2011, Ginger Buchanan (senior editor at Tor) asserted that there has never been a runaway science fiction bestseller.  In the eyes of New York publishing, that may be true–but New York has a notorious record for missing the catch in pursuit of one big fish.  Because of epublishing, whole new genres like New Adult that publishers thought would never sell are now going mainstream.

And even the niches that stay niches are becoming quite lucrative for the authors who can build a decent following.  When author cuts out the middlemen and develops a direct relationship with the readership, it only takes a thousand true fans or so become a financial success.  As Kris Rusch pointed out so aptly, those numbers may bring only scorn from New York, but for the writers who actually produce the content, that’s a vein of pure gold.

I can’t tell you how many success stories I’ve heard from fellow sci-fi writers over on the Kindle Boards, who started just for the grocery money and ended up quitting their day jobs.  But as Hugh Howey pointed out, the runaway bestsellers are not the true story of the epublishing revolution–it’s the little guys who only sell a few hundred copies a month but are earning enough to support themselves writing what they love.

Indeed, we’re already starting to see an explosion of new science fiction, thanks largely to the ease of electronic self-publishing.  I’ve only read a few of them so far, but Nathan Lowell stands out among them, as well as my good friend Kindal Debenham.  These guys and so many others are bringing a fresh new voice to space opera, revitalizing the genre in ways that simply weren’t economical back in the days of Big Publishing.

So even if space opera as a literary genre isn’t quite large enough to go mainstream, it is large enough to support a wide range of new voices under the emerging business models.  And as the epublishing revolution continues to mature, I think we’re going to see a new golden age comparable to the era of the pulp adventure stories.

I’ve been publishing my own work since 2011, and I can attest that there’s never been a better time to be a writer.  I’m not quite making enough to go full-time yet, but at the rate things are going, it will only be a  year or two before I realize my dream of making a living telling stories that I love.  And if they’re the kind of stories that you love too, then that’s great news for all of us!

So has science fiction reached its zenith?  I don’t think so.  It went mainstream about a generation ago, which was definitely a huge moment, but for the last few decades it’s been in the process of branching out and rediscovering itself.  Right now, I think we’re on the verge of a wonderful new renaissance that is going to blow us all away.  As a lifelong reader and writer of science fiction, I certainly hope that’s the case.  And because of the reasons listed above, I sincerely believe that it is.

U is for Universal Translator

In science fiction, whenever two characters from different planets or different alien races have to interact with each other, they almost always speak the same language or have some sort of universal translator that magically makes them able to communicate with minimal misunderstandings.  This is especially common in Star Trek, though it happens in just about every franchise involving a far-future space opera setting of some kind.

I’ve got to be honest, I think this is a cheap plot device that almost always weakens the story.  As a writer, it’s tempting to have something like this so you don’t have to deal with any pesky language barriers, but when you do this, you remove a major potential source of conflict, thus violating the rule of drama.  Also, you make your fictional universe feel a little less grand, your aliens a little less alien.  After all, if everyone can perfectly understand each other, then there must not be a huge difference between Earth and the far side of the galaxy.

There are some times when having a universal translator allows you to broaden the story and focus on other conflicts.  For example, if some sort of interstellar legislation is under review in the grand galactic council, you can’t spend all your time focusing on basic communication difficulties.

However, if this is the case, then you can usually overcome the language barrier through other means–a galactic lingua franca, for example, or translation tools that may or may not misfire on occasion (much like Google Translate).  Of course, if you’re writing a comedy like Galaxy Quest (or parts of Star Control II), then falling back on a universal translator is forgivable.  But if you’re going for believability and a sense of wonder, this trope isn’t going to do you any favors.

While linguists and technologists have been working on translation programs for some time (and admittedly making some significant breakthroughs), I’m extremely skeptical that we will ever develop a perfect universal translator in real life.  If we do, I expect we will have to develop a sentient AI as a prerequisite, since the nuances of language are so inseparable from the things that make us human.

Here’s how translation services like Google Translate work:

  1. They amass an enormous database of language material by scanning websites, newspapers, and other documents.
  2. They analyze this database to look at word combinations and frequencies, observing the likelihood that any one word will appear in combination with any others.
  3. They compare these combinations and frequencies with those in other language databases to match words and phrases.

This data crunch method of translation works fairly well for simple words and phrases, but it falls apart in the more complex grammatical structures.  I see this any time I try to use Google Translate with an Arabic source.  Arabic is an extremely eloquent language, with all sorts of structures that simply don’t work in English.  One mistranslated word can completely change the meaning of the entire text, and even when it works, the technically correct English translation sounds as if it’s full of errors.

The methodology also falls apart for languages that are too small to have much of an electronic database.  The Georgian language is a good example of this.  It’s spoken by only about 4.5 million people worldwide, most of them in the country of Georgia, which is predominantly rural.  Internet access for most of the population is very limited, and most Georgians who do communicate online tend to use the Roman or Cyrillic alphabets more often than their own.  As a result, Google Translate for Georgian is utterly useless–seriously, you’re better off just sounding out the letters and guessing at the meaning.  There are some other sites like translate.ge that try to fill the gap, but they seem to rely on actual lexicons, not databases and algorithms.

All of this is between entirely human languages that developed in parallel on the same planet–indeed, languages between human cultures that have traded and shared linguistic influences for thousands of years.  What happens when we encounter an alien race whose biology makes it impossible for them to make human-sounding noises?  Or an alien race that communicates through smell or electromagnetic impulses instead of sound?  What happens when humanity is spread out across hundreds of star systems, each of which periodically becomes isolated from the others for hundreds or even thousands of years?  When our definition of human is stretched so thin that we would not even recognize our far-future descendents as anything but alien?

There is so much wasted potential whenever a science fiction story falls back on a universal translator.  Case in point, compare Halo I, II, and III with Halo: Reach.  In the first three games, the Master Chief’s universal translator enables him to hear exactly what the enemy Covenant troops are saying.  This is great fun when you’re chasing down panicked grunts, but it tends to get old after a while.  In Halo: Reach, however, the human forces haven’t yet developed a universal translator, so everything the Covenant say is in their original language.  All of a sudden, the game went from a hilarious joyride to a serious war against aliens that felt truly alien.  That one little change did wonders to the tone and feel of the entire game.

Needless to say, you won’t find a universal translator in any of my books.  In Star Wanderers, the language barrier is the heart and soul of the story–it’s a science fiction romance between two characters from radically different worlds who don’t speak the same language, and yet overcome that to develop a strong and healthy relationship.  In Sholpan and Bringing Stella Home, Stella knows a language that is fairly similar to the one spoken by the Hameji, but there are still words and phrases that elude her.  This detail is critical because it impedes her ability to understand and adapt to the Hameji culture, leading to some major conflicts later in the book.

As someone who’s lived for significant periods of time in Europe and Asia and learned languages very different from English, I can say that the language barrier is not something that we as writers should avoid, but something that we should embrace.  There are so many interesting stories that can be told when two characters don’t speak the same language.  Please, don’t be lazy and write that out of the story through a cheap plot device!  Let your aliens be truly alien, and your worlds and cultures so fantastic that we can’t help but feel hopelessly lost in them.

P is for Planets


Gliese 581 by ~arisechicken117 on deviantART

One of the best things about a good science fiction story is that it can take you to another world–literally!  Well, not in the sense of actually physically taking you there, but if you want to experience the thrills of an alien world from the safety of your favorite chair, the best way to do it is to immerse yourself in a good space adventure story.

Planets are to science fiction what islands and continents are to fantasy.  It’s possible to tell a story where no one ever sets foot on one, but then you’ve basically got a sea story (since space is an ocean, at least in most space opera).  Even then, your characters are probably going to put into port from time to time, if for nothing else than a change of scenery to make things interesting.  And if there’s anything science fiction interesting, it’s the wide variety of possible planet types.

For example, what would a planet be like if it were covered completely by water?  If the world-ocean was so deep that there was no visible land?  Assuming that the planet orbits within its sun’s habitable zone, where the temperature ranges allow water to exist as a liquid, then you would have a pretty interesting place.  What would the hurricanes be like?  A lot more intense than the ones here on Earth, that’s for sure.

Then again, suppose that the planet was a bit closer to its sun, and most of that water existed in the atmosphere as a gas.  You’d have some pretty intense atmospheric pressures on the surface, but the density of the atmosphere would make it much easier to keep airships and flying castles aloft.  In fact, that might be the most practical way to settle that kind of a world.

In our own solar system, there is an incredible amount of variety.  On Mars, for example, glaciers of dry ice cover the southern pole, while the sun sets blue in a normally dirty brown sky.  The tallest mountain actually summits above the atmosphere, and every few years, dust storms cover the whole world.  And believe it or not, Mars is a lot more similar to Earth than anything else in our solar system.

On Titan, rivers of liquid methane flow down mountains of water ice, while black carbon dunes drift across a desert shrouded in orange haze.  While the sun rises and sets with predictable regularity, the planet Saturn is suspended at the same point on the horizon and dominates a large portion of the sky.  Don’t expect to see any rings, though–Titan orbits along Saturn’s ring plane, so the rings are mostly invisible.

Europa, one of the four Galilean moons of Jupiter, is also dominated by its host planet.  Water ice covers the surface, but deep, deep below, there’s a massive liquid ocean that has never seen the light of the sun.  What sort of monsters lurk in those depths–an ocean buried beneath a world?

Jupiter itself is pretty intense.  A gas giant world with swirling bands of planet-sized clouds, it hosts a monstrous hurricane large enough to swallow at least two Earths.  This vortex has been churning across the planet for over 150 years, and possibly as much as 350.  I still remember the chills I got when I read 2001: A Space Odyssey, and the scientists’ probe dropped through the haze to a cloud deck as massive as one of our continents here on Earth.

Gas giant planets can be really interesting.  They aren’t human habitable, since the gravity and pressure are so intense that anything man-made would be crushed before it could hit the surface, but those same forces can lead to some other interesting things.  For example, at the lower levels, you may find storms that rain diamonds.  Go further still, and you find an intense magnetic core that’s just on the verge of being able to sustain nuclear fusion.  Detonate enough nuclear material down there, like they did in a short story from the Halo universe, and you can turn the planet into a star.

And that’s just our solar system.  What about the hundreds of exoplanets that astronomers are now discovering?  The first one to be confirmed, believe it or not, was orbiting of all things a pulsar!  Imagine that–instead of the life-giving rays of a sun, the planet is bathed in highly lethal X-rays and gamma rays.

Of course, there are plenty of planets orbiting stars like our sun, but most of the ones discovered so far are hot Jupiters–gas giant worlds that orbit so close to their sun that the years are measured in hours.  Some of these planets are so close that the sun is actually blasting the atmosphere away.  We haven’t discovered the rocky core of a gas giant world that’s been destroyed in this manner, but theoretically it could exist.

Or what about the planets with highly elliptical orbits that traverse the habitable zone of their stars?  Imagine: a world where the winters are so cold that the oceans freeze solid.  After several of our Earth years, the spring brings a massive thaw.  For a few short months the weather is actually quite balmy.  Then, as spring turns to summer, the heat grows more and more intense, until the oceans begin to boil!  When the summer reaches its zenith, the planet is nothing but a scorched desert wasteland.  Soon, though, the autumn cool brings back the rains, with storms so intense that they refill the oceans in just a matter of months!  Then, the deep freeze of winter begins, and the world returns to its long icy tomb.

One of my favorites, though, is the ribbon world that Asimov predicted in some of his stories.  Worlds like this occur most commonly at class M red dwarf stars, which are so cool compared to our sun that planets within the habitable zone are tidally locked.  This means that the sun neither rises nor sets, but remains stationary in the sky.  The day side is burning hot, with either a barren desert wasteland or a giant hurricane large enough to cover most of the hemisphere.  The night side, on the other hand, is so cold that all the water is completely frozen.  The only habitable parts of the planet exist in a ribbon-like swath where the sun is just on the other side of the horizon, casting the land in perpetual twilight.

Believe it or not, we’ve actually discovered a planet like this in the Gliese system.  Gliese 581g, or “Zarmina’s World” as the lead astronomer dubbed it, was discovered back in 2010.  I was so excited by the discovery that I dedicated a blog post to it.  Since then, the findings have not yet been confirmed, so it isn’t safe to call it a planet for sure, but if/when it ever is confirmed, it may be one of the first truly Earth-like planets to be discovered (at least, as Earth-like as a ribbon world can be).

In much of science fiction, there’s a tendency to make planets single biome only.  Thus, you have your desert planets (Arrakis, Tatooine, Gunsmoke), your ice planets (Hoth, Gethen), your ocean planets (Calamari, Aqua), your jungle/forest planets (Dagobah, Lusitania, Kashyyyk), and even planets that are nothing but giant cities (Trantor, Coruscant).  Some of the more recent series like Halo try to avert this, but even today it’s still fairly common.

If there’s anything that modern astronomy is showing us, though, it’s that the variety of planets and worlds out there is beyond anything we could possibly imagine.  This is why I get a bit irked when an otherwise excellent series like Firefly makes out every planet to be like Wyoming.  What about Gliese 581gKepler 22bGJ 1214bKepler 16b?

As more exoplanets are discovered, I can’t help but believe that science fiction is going to experience a paradigm shift.  What was once purely the realm of imagination is now being confirmed as reality.  Alien worlds exist–alien Earths, even.  And just as our conception of Mars changed from the Sword & Planet tales of Edgar Rice Burroughs’ Princess of Mars to the hard sf epics of Kim Stanley Robinson’s Red Mars, Green Mars, Blue Mars, so will our conception of other alien worlds.

I’ve got a lot of different planets in my own books, some borrowing a lot from the recent exoplanet discoveries, others leaning closer to the single biome worlds of classic space opera.  In Desert Stars, Gaia Nova is kind of a cross between Arrakis and Trantor, with giant domed arcologies covering half the planet’s surface while the rest is mostly desert and wasteland.  In Bringing Stella Home, Kardunash IV is (or rather, was) an Earth-like world, with forests, mountains, and oceans.  In Stars of Blood and Glory, New Rigel is a straight up ocean world, while Ebitha from Star Wanderers is an ocean world tidally locked to its dwarf M class sun.  I haven’t yet played with the elliptical planet, but I probably will someday.

One of the things I love most about a good science fiction story is that it takes me out of this world.  With all the incredible new discoveries that astronomers are making, that aspect of the genre is only bound to get better.  They’ve certainly enriched my own work, and will doubtless continue to do so in the future.

H is for Hologram

cortanaIn real life, the term “hologram” means something fairly specific.  But in science fiction, it can mean a number of different things.

For example, in Star Wars it’s basically a three dimensional video recording projected on a flat surface.  In Halo, it’s the visual form that the AI character Cortana takes when she wants to interact with the Master Chief.  And in Star Trek, the holograms actually have a degree of physical substance, so that in some episodes they go rogue and try to take over the ship.

The basic underlying idea, though, is the same: blurring the line between the virtual world and the real world through a virtual projection that we can interact with.  And in that sense, this is actually an area where science fact is fast catching up with science fiction.

Some sub-genres, such as cyberpunk, focus almost solely on the tension between the real and the virtual.  Often set in a near-future world, cyberpunk stories often feature a crapsack future, from which the only meaningful escape is a virtual reality.  But the thing about virtual realities is that they can be reprogrammed in such a way as to give the ones controlling it almost absolute power over the lives of the people inside.  For that reason, the main characters are often hackers, struggling against the corporate evil overlords.

But holograms aren’t restricted to cyberpunk.  They’re quite common in space opera, too, and not just because they’re cool.  For one thing, they can be really useful for training simulations (which often leads to holodeck malfunctions, courtesy of the rule of drama).  They can also be useful as disguises or decoys, especially in the Halo series.

But perhaps the most memorable holograms are the ones who develop a close relationship with their real-world human counterparts.  This may include romance, which, combined with the existential angst that typically surrounds androids, robots, and cyborgs, makes for some very interesting tension.  A good example of this is Cortana from the Halo series, an alien AI who took on a younger form of her human handler, Doctor Halsey, and then developed a very close relationship with her Spartan bodyguard, the Master Chief.  It never actually went anywhere (at least in the main series arc), but it certainly made for an interesting story.

Jane from the Ender’s Game series would probably be my favorite hologram, though she’s more of a shapeshifting AI who can take many different forms, depending on what suits her.  Cortana is definitely up there too.  I haven’t used this trope much in my own fiction yet, but I’m playing with it in Heart of the Nebula, a currently unpublished direct sequel to Bringing Stella Home.  Not sure exactly where I want to take it yet, but it should be interesting.

C is for Cryo

halo_cryochamber

I think every science fiction writer has a cryo (aka “human popsicle“) story sitting around somewhere, even if it’s just in the back of their head.  It’s one of those tropes that keeps coming back, just like the alien invasion, the robot apocalypse, and the Adam and Eve plot.

The basic concept is pretty simple, even if the technology is a bit more complex: a human or animal undergoes rapid freezing in order to put themselves into stasis for an extended period of time.  Months, years, or even centuries later, someone thaws and resuscitates them so that they wake up in a completely different time and place.

There are a lot of good reasons why going into cryo makes sense in a science fiction universe.  One of the more common ones is that the characters are colonists on a mission to an alien star, and their spaceship doesn’t have a faster-than-light drive.  Rather than go through all the trouble of building a generation ship, the designers instead built a series of cryo chambers to put the colonists into stasis for an extended period of time.  It might take centuries or millennia for the ship to reach its destination, but when it does, the colonists wake up as if it’s just been a long, dreamless night.

In The Worthing Saga, Orson Scott Card has a somewhat unusual rationale behind the prevalence of cryo in his universe (though they call it “hot sleep,” and it’s induced by a drug called soma).  Only the rich can afford the technology, and the imperial overlords very carefully regulate the use of it so that there’s a clear hierarchy based on who goes under for the longest amount at a time.  It’s a way for the citizens to achieve a simulated form of immortality, by skipping five or ten years every year or two of their lives.

In the Halo video game series, the UNSC uses cryo as a way to preserve their greatest military assets, the Spartans, for the times when they’re needed.  The first game in the series starts when John-117, aka the Master Chief, is awakened just as the starship Pillar of Autumn crash lands on a mysterious alien structure.  Like something from an old Norse legend, the third game ends when the Master Chief seals himself into the cryo chamber of a derelict starship, telling the AI Cortana “wake me when you need me.” (highlight to view spoilers).

So why are cryo stories so prevalent in science fiction?  For one thing, they’ve been floating around in our cultural subconscious a lot longer than the genre has been in existence–just think of Sleeping Beauty or Rip Van Winkle.  For another thing, the science is not that far-fetched.  Certain animals can be revived after extended periods of frozen stasis, and according to the New York Times, it’s happened at least once with a human being.  Science fiction has a long history of turning fiction into fact (for example, Arthur C. Clarke and communication satellites), so perhaps it’s only a matter of time before human cryotech becomes a reality.

I’m definitely a fan of this trope in my own writing.  Genesis Earth has a chapter with a rather horrific cryothaw scene, which I later spun off into a short piece titled “From the Ice Incarnate.” I haven’t played with it much in my latest books, but in Heart of the Nebula which I hope to publish later this year, the cryotech plays a very important role in the plot.  And if I ever write a prequel to my Gaia Nova series showing how that universe got started, it will feature a cryo colonization story.  The main premise of that series is that a group of human colonists fled 21st century Earth and went into cryo to colonize a distant corner of the galaxy, but when they woke up, they couldn’t find Earth anymore, so it became something of an ancient holy legend (which is a major driver for Desert Stars).
