From the four strata of Crimson City come rogues: vampire, werewolf, human, demon. These rebels, rakes and unsung heroes have turned their backs on the extravagant vampire skyway, the gritty werewolf underground, the iron-fisted human stronghold and the fiery power of the demon underworld. Walking a thin line between heaven and hell, they make their own rules and follow their own destinies. They will be the ones to determine if the City flourishes or fails.

Cydney Brighton knows them well, for she too is now rogue. Having escaped hell, she's discovered that the City is not what it once was--and neither is she. Only one man understands her, understands what it means to be someone or something beyond control. He's ready to come out of the darkness; and part-man, part-machine, he's willing to sacrifice almost anything to make himself whole.
