Jericho - The Hybrid Chronicles, #1

He had made the ultimate sacrifice...only he wasn't really dead. He signed their forms. He accepted their diagnosis. He welcomed the treatment. He changed his name and disappeared. Now he is treated as less than human. A pet, held in the Facility until he and his team are let loose on a government-sanctioned target. Except this next target isn't some terrorist or criminal - it's a teenage girl on US soil, along with the woman who stole his heart.
Jericho and his team may be a different kind of soldier, but they still hold to their moral codes and honor. Going against a direct order is not something they would normally consider... But nothing about this team is normal.
