Six months after a case gone bad infected him with lycanthropy, private eye Ben Lockwood hasn’t simply come to terms with his new condition; he’s embraced it. The animal lets him just be instead of dwelling on past horrors, and he frequently sleeps better as a wolf. He thinks he’s fine, until a couple of supernatural law enforcement agents inform him that if he wolfs too much, he’ll forget his humanity—leaving them with a mess to clean up. And then one of those past horrors comes roaring back into his life. Rutger Ostheim, enraged by the death of his family, breaks out of prison to seek vengeance. He’s aided by a ruthless businessman with slippery ethics and a separate grudge, who’s taken the werewolf nanotech to new and awful heights, determined to sell it to the highest bidder. No matter what they want Berserker Virus Murder-Wolf tech for. However, when Ben is given the opportunity for some payback of his own, he may find his inner demons a far graver threat than a tech-enhanced werewolf nearly twice his size.
