Treadstone nearly destroyed Adam Hayes. The top-secret CIA Black Ops program trained him to be an all-but-invincible assassin, but it also cost him his family and any chance at a normal life. Which is why he was determined to get out. Working as a carpenter in rural Washington state, Adam thinks he has left Treadstone in the past, until he receives a mysterious email from a former colleague, and soon after is attacked by an unknown hit team at work.
Adam must regain the skills that Operation Treadstone taught him – lightning reflexes and a cold conscience – in order to discover who the would-be killers are and why they have come after him now.
