Rogue Sequence

It's 2091 and independent contract companies around the world are producing genetically modified soldiers...to be sold to the highest bidders.
Ander Rade is a super-soldier, a genetically engineered living weapon, and has been dutifully following orders since he gave himself to Scythe Industries' Gene-Mod Program several years ago. But when a mission goes sideways, he's captured, imprisoned, and forced into brutally violent fighting pits for the better part of the next decade...until agents from the Genetic Compliance Department of the United American Provinces appear in the visitors room.
Things have changed since Rade was captured. Shortly after his incarceration, the World Unity Council banned human genetic engineering and deemed all modified individuals a threat to society. Overnight, an entire subculture of people became outlaws simply for existing. But instead of leaving Rade locked behind bars, the GCD agents have come with an offer: Freedom in exchange for his help tracking down one of his former teammates from that ill-fated mission all those years ago.
It's an offer Rade can't refuse, but he soon realizes the situation is far more volatile than anyone had anticipated, and must take matters into his own hands as he tries to figure out whose side he's really on, and why?
