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 micro-gravity.

In charge of the murder investigation is Nikki "Fix" Freeman, who is not thrilled to have Alice Blake, an uptight government goody-two-shoes, riding shotgun. As the bodies pile up, and the partners are forced to question their own memories, Nikki and Alice begin to realize that gang warfare may not be the only cause for the violence.
