Forbidden — Kelley Armstrong

The team-spirit sign by the side of the highway seems a good omen to loner Morgan Walsh, as he drives to what could be the most important visit of his life--a chance to join the North American Pack. Then he wakes naked in the woods, surrounded by wolf tracks and a ring of suspicious cops. The situation only gets worse when he's bailed out by Alpha-elect Elena Michaels and Clayton Danvers, her terrifying enforcer and mate.

Disappointed that such a promising young werewolf risked exposing them, Elena isn't expecting anything from the pesky retrieval job except some much-needed alone time with Clay. Instead, she finds a different kind of evil stalking the streets and forests of Westwood, New York. Trapped in town by a snowstorm and sabotage, Elena, Clay and Morgan must find the mysterious threat before it sets its sights on them.
