A propulsive science fiction tale of murder and memory, all set on a futuristic space station. Hundreds of miles above Earth, the space station Ciudad de Cielo - the City in the Sky - is a beacon of hope for humanity's expansion into the stars. But not everyone aboard shares such noble ideals. Bootlegging, booze, and prostitution form a lucrative underground economy for rival gangs, which the authorities are happy to turn a blind eye to until a disassembled corpse is found dancing in the microgravity.

The enigmatic Greys have returned, bearing a host of stunning revelations regarding their role in Earth’s history, the Pelarans, and humanity’s place in the cosmos.

Their mission: enlist the help of enough Guardian spacecraft to put an end to the out-of-control, tyrannical AI before its forces can reach Earth.

Trapped on an alternate Earth, the combined crews of a crashed Russian spaceship, a British expeditionary force and a group of strays from the future must work together to survive, escape and discover what led them to this point.

Though she feared the worst, after meeting Darla, Tanis realizes that having an AI - especially a fabulously wealthy one - is better than she'd ever imagined. Darla foots the bill for Tanis to enjoy her convalescence.

It is the distant future. The world known as Virga is a fullerene balloon three thousand kilometers in diameter, filled with air, water, and aimlessly floating chunks of rock. The humans who live in this vast environment must build their own fusion suns and "towns" that are in the shape of enormous wood and rope wheels that are spun for gravity. Young, fit, bitter, and friendless, Hayden Griffin is a very dangerous man. He's come to the city of Rush in the nation of Slipstream with one thing in mind: to take murderous revenge for the deaths of his parents six years ago.
