What happens when the geeks inherit the Earth? For starters, things get a little weird.

In the year 2475, the remnants of humanity have taken to the skies, inhabiting massive domed cities that hover five miles over the ruined ecological disaster of old Earth. The Powers That Be, in their infinite wisdom, decided that the few million people left deserved to live their best lives, so they gave each sub-orbital platform its own theme and legally enforced tech level. Named for afterlives and sacred places from all of the world's great cultures, Elysia, A'Aru, Valhalla, Tian and the other orbitals range from cyberpunk metropolises to Tolkienesque medieval fantasy lands; from Victorian steampunk cities of glass and copper to snowbound Viking kingdoms.

Not content with merely cosplaying their days away, a significant portion of the population have become transhuman "cybernaturals," electing to transform into creatures from myth through cybernetic enhancements and advanced genetic therapies; orcs, dwarves, elves, vampires and werewolves now exist through super-scientific means, not supernatural ones.

In the middle of this madness, Daniel Davidson, a pop culture archaeologist and mercenary of dubious repute and his band of foul-mouthed friends are charged with tracking down an ancient book that could, in the wrong hands, erase all of reality. It could be a huge payday and might even involve saving the known universe as a tidy bonus. That is, if they manage to NOT die at the hands of cannibal sex cultists, swashbuckling rogue vampires, prankster demigods, Templar knights, horrifying biblical angels, the angry star-spawn of elder things, and Satan himself. And possibly food and/or alcohol poisoning. Or suffocation in a sex dungeon.

It's a filthy, hilarious, epic journey through an off-kilter future filled with bullets, blades, beasts, and boat drinks. If you like your profane sci-fi action comedies with a side order of urban and traditional fantasy, look no further.
