Detective Maxim Dwyer has spent two years chasing leads about his wife's disappearance in the isolated Arizona town of Sycamore. Every trail leads to the Seventh Sons motorcycle club — and the rumor that its members are werewolves. Then a bar brawl turns fatal, forcing Maxim into an uneasy alliance with enigmatic outlaw Diego de la Torre, who has his own reasons for probing the club's secrets. The paranormal is just the icing on what turns out to be a deeply human crime story.

Maxim Dwyer is methodical, grief-driven, and stubbornly fair — the kind of detective who presses witnesses until someone breaks, even when that someone might be seven feet tall and very angry. Diego de la Torre is his perfect foil: fluid where Maxim is rigid, comfortable with moral grey zones where Maxim demands black and white.

Three books move from a tight werewolf mystery in Sycamore's outlaw biker world to increasingly strange supernatural terrain. Book 2 doubles down on the MC's pack dynamics and a rival biker war. Book 3 largely sets aside the werewolves for a chilling missing-child mystery, showing that Maxim and Diego as a duo outlast any single supernatural threat. The series demonstrates confident genre-mixing: noir procedural, paranormal thriller, and Arizona wilderness Gothic.
