Rhys Cooper’s unique immunity to all three strains of the virus that nearly annihilated humanity has brought him the unwanted attention of Clean Zone scientists. They’ve summoned him for testing—ostensibly in the hopes of finding a vaccine—but Rhys’s partner, Darius Murrell, has good reason not to trust any government. He and his comrades in Delta Company were unwitting test subjects for Project Juggernaut, the military experiment that gave them superhuman abilities and unleashed the pandemic. Doubting the government’s intentions, Delta Company refuses to let Rhys go alone. Fear of infection has kept Zach Houtman and his lover Nico Fernández apart for a decade. They meet rarely, just long enough to coordinate their spying on the head of the government’s virus research division. Secretary Littlewood is a vicious predator, and they suspect he’s trying to acquire the strain of the virus that would make him superhuman. To stop him, they need the perfect bait: Rhys. For Rhys, helping them might cost him his relationship with Darius—or his life. For Zach and Nico, even if their plan succeeds, they still face the ultimate question: can infected and uninfected people ever live together safely?
