The Duality Paradigm
Everyone knows magic users and werewolves are intrinsically diametrically opposed...
Seattle Police Detective Ethan Ellison, born into a long line of Quebecois magicians, leads a fairly unassuming life working Theft and consulting on magical misdemeanors. He’s spent eight years building a life for himself in Seattle, far from his father's shadow. He works hard, lives under the radar, and fucks whoever catches his eye.
Detective Patrick Clanahan, beta-heir to Pack McClanahan, is a tightly wired bundle of rage and guilt, still trying to come to terms with the murder of his last partner.
When a human woman is murdered in werewolf territory under suspicious circumstances, Ethan is reassigned to worked the case with Clanahan in the hopes that he'll be able to balance out the wolf's rougher edges.
Too bad they mostly just rub each other the wrong way.
