Evin KinKaid has it all: the title of alpha of the KinKaid wolf shifter pack and the man he loves, his mate, Mason Thorne II in his bed. But across territorial lines, it seems another pack is conspiring to see just how badly he wants to keep them both. So when the Gregorson pack tests its boundaries, leaving Evin to find his home ransacked and his mate nowhere to be found, the rival shifters learn what it's like to gain the KinKaid's alpha's full attention.
