It's up to the Hartland pack, led by Alpha Amos, to protect Craig as they try to persuade the Hawkriggs of the danger they face, courtesy of Amos's brother, Howard--who is still trying to undermine Amos with potentially deadly results. Meanwhile, Carter Ruin's brother, Charlie, has been busy, too, and is determined to bring his family back together...at all costs. After years of abuse, Charlie is damaged goods and highly dangerous. Meanwhile, Carter and Elvis finally meet their mates. Will it be plain sailing, or will the danger brewing destroy everyone's chance at happiness?
