A beautiful hæmophage infected with a virus that gives her superhuman powers has to protect a boy in a futuristic world, who is thought to be carrying antigens that would destroy all hæmophages.

Human society has been decimated by a holocaust caused by biological warfare research gone wrong: instead of creating super-soldiers, a genetically-engineered virus turns infected humans into Hemophages, a vampire-like sub-species with enhanced physical abilities. In the infection-paranoid and technologically advanced society that follows, Violet is a singular Hemophage warrior battling the totalitarian dictator who is determined to wipe out her species at any cost.
