She moved to Sweetwater Falls and accepted the job as the town’s Sheriff to escape from the pain of her dark past. But a fresh start in the once idyllic town came with many unexpected twists... Fortunately, with her new friends, a new sense of family and community, and a blossoming relationship with Ryker, Spenser felt a sense of peace and contentment.

Unbeknownst to her, the past was rising like a dark shadow, intent on destroying the people she loved and the community she vowed to serve. When Spenser is called out to a brutal sexual assault, she uncovers a pattern of similar assaults in the surrounding towns. More disturbingly, Spenser finds that the women in this string of assaults all bear a striking physical resemblance to her. Each attack is more vicious and brutal than the last, and it isn’t long before Spenser’s worst fears are realized. How do you fight a monster that seems to know you better than you know yourself? There’s a dark shadow covering the Falls and Spenser will need the help and comfort of Ryker and his Lab, Mocha more than ever before.
