Two years after his wife went missing, Detective Maxim Dwyer is still running down leads. The isolated woods of Sycamore are home to many lawless men, and no one's talking, but that hasn't stopped Maxim from gathering suspects. Topping his list is the local motorcycle club, the Seventh Sons. His biggest obstacle? Everyone swears the bikers are werewolves. The small-town residents are wary of provoking the MC, and the marshal's office is no exception. Everything changes when a routine biker brawl turns fatal. Going against procedure, Maxim presses an enigmatic stranger for answers. But Diego de la Torre is running his own con. The outlaw deals in lies and legends, and no adversary can back him down. Not even the police. It's too bad that nobody's above the law for Maxim. He's willing to risk his badge, and his life, to prove it.

Diego de la Torre is officially an outlaw now, a full-fledged member of The Seventh Sons Motorcycle Club. The werewolf MC runs the wild lands of Sycamore with ease. At least until a dead body shows up and points to them as the culprits. Detective Maxim Dwyer presses the Seventh Sons hard, but there are other guns in play. California bikers look to expand their drug trade. A mercenary outfit seeks revenge. Top that with an overbearing FBI agent who undermines local police, and both detective and outlaw have their hands full. Brothers or not, Sycamore's about to get a whole lot bloodier.

Maxim and Diego don't always get along. But they get results. After missing for three days, a young girl is found wandering the Arizona forest. She's despondent, with no memory of her ordeal beyond eerie delusions. When a second girl disappears, a pattern emerges that sets two police departments racing against the clock to save her. Only two men dare take on the mysterious Sycamore wilderness: Maxim Dwyer is a small-town detective with attachment issues who faces off against a rival from the county police. Diego de la Torre, a biker troublemaker with an anti-authority complex, walks a fine line between responsible citizen and vigilante outlaw. Together, the unlikely pair isn't always on the same side of the law, but they are the girl's best hope. Unfortunately, things in Sycamore are rarely what they seem. Maxim and Diego have more problems than they know, and if those don't catch up with them, whatever lurks in the forest will.
