Stiles runs away during his first heat, right into the waiting and ambiguously scary arms of the Alpha's nephew, Derek Hale. He doesn't have any choice except to submit, but along the way, he digs up a mystery that threatens his family and even the town's safety.

Derek's fourth Chase will be his last if he doesn't catch an omega this time. He's starting to doubt this whole soul-mate thing anyway, at least until someone from his past shows up and gives him the run of his life.

Stiles runs away from his old pack on a Monday. He meets his dad for the first time on a Sunday, and he falls in love on a Thursday.
