An undercover FBI agent has been exposed—while a traitor hides within the Bureau in this heart-pounding crime thriller by “a knock-em-dead writer” (Anthony Neil Smith, author of Slow Bear).

Tony Wolf, a troubled man and the FBI’s most esteemed undercover agent, is back after mysteriously vanishing without a trace. A specialist at infiltrating criminal organizations and taking them down from the inside, he lives his life in the shadows.

But when he’s forced into the open during the rescue of two kidnapped children, Wolf becomes caught up in a massive federal manhunt. Faced with a traitorous agent and a ruthless, renegade biker gang he has crossed paths with before, Wolf finds himself in danger. And when he realizes that the double agent is helping the gang, Wolf sets out on a lethal mission to uncover the truth, no matter the cost.
