Marsalis is one of a new breed. Literally. Genetically engineered by the U.S. government to embody the naked aggression and primal survival skills that centuries of civilization have erased from humankind, Thirteens were intended to be the ultimate military fighting force. The project was scuttled, however, when a fearful public branded the supersoldiers dangerous mutants, dooming the Thirteens to forced exile on Earth’s distant, desolate Mars colony. But Marsalis found a way to slip back–and into a lucrative living as a bounty hunter and hit man before a police sting landed him in prison–a fate worse than Mars, and much more dangerous.
