The Seventh Sons. Sycamore Moon, #1

"Supernatural meets Sons of Anarchy. Detective Maxim Dwyer is a man on a mission and nothing is going to stop him from finding his missing wife - not shape-shifting hard cases, outlaw bikers, or government cover-ups. Finn's Seventh Sons is a story you're not going to want to put down."- James A. Hunter, Author of Strange Magic (Yancy Lazarus Series) 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.
