"It's happening again, Aidan. We didn't stop it, after all." As an elemental, Aidan Brook holds the power of water at her fingertips. A descendant of the earth's oldest magic, she can cause tides to ebb and flow, put out house fires without calling 911, and give anyone who's annoying her an impromptu shower. But even her magic has its limits. After it fails her one terrible night, she hides from the world and everyone she once loved, trying to escape the memories that haunt her. Ten years later, her exile is brought to an abrupt end when her former best friend appears on her front porch. An elemental killer is once again murdering her friends, and she must return to the scene of her own crimes. Lake Tahoe proves more than she bargained for. Between a sadistic killer, some clever FBI agents, an annoyingly attractive landlord, and way too many new roommates, she has a pretty full plate. Add in a past she's desperate to escape and her own uncontrollable powers, and Aidan Brook is having a very, very bad month.
