As a mermaid, Brooke has never been to the Rocky Mountains. And stumbling across the murder of a werewolf is not a great start to her visit. In the paranormal-only town of Purgatory Falls, though, she's discovered a place where she can reveal her true self for the first time in her life. So she shakes off her unease and tries to enjoy herself, exploring the quaint small town and getting to know its residents, including a dragon shifter police officer. When the official investigation into the crime she witnessed seems to narrow in on the wrong suspect, however, Brooke realizes she might have to start poking around on her own-and begin to test her own magical abilities.
