After a childhood tragedy, Melanie Cook had shut out all people from her life, preferring to be alone over getting hurt again. On duty one night, she is attacked by a mountain lion shifter and thrust into a world she never knew existed. She is put into protective custody by four enormous and handsome men, men she just can't seem to stop desiring. She is feeling things she never imagined she would. These men threaten to break her years of disciplined solitude. Finn, Cooper, Hunter, and Dane Frederick have lived a long time waiting to find their mate. They find her on a night of blood and death. Determined to keep her safe and to make her theirs, they take her home. But explaining the existence of shifters to their human mate, and having her accept them for who they are, is not easy with the continued threat on her life.
