Agent Zero. Viral Agents, #1

After barely surviving an IED while serving his country, Reese was whisked away by a shadowy government agency and somehow... enhanced. Now he's an agent-smarter, faster, stronger, deadlier-and executes his missions with cold precision. But when he's inexplicably drawn to a down-on-her-luck waitress, Reese learns he's not the emotionless killer he thought Division had made him. One minute Holly Candless is getting fifty-buck tips from a strange but seemingly harmless customer.
The next, she's kidnapped, nearly killed, and rescued by Reese. Suddenly, they're on the run from the very government that wants Reese reprogrammed-and Holly dead. Now keeping Holly alive is not only Reese's primary mission, it's his sole chance at redemption... ...and their only shot at survival.
