Falling in love can be murder …

No one in Lily Lennox's life can understand why, for each of the past five summers, she has left her successful business behind to work a lifeguarding job at the exclusive Riovan Wellness Resort on a sun-soaked Caribbean Island.

Fortunately for her, they also aren't aware of the mysterious deaths that occur on the island every time she's there. You see, Lily has a secret. She's determined to make toxic people pay for the damage they do—and she's very good at getting away with it.

But this summer, there's a problem in the form of a very attractive guest, Daniel Black, who is asking a few too many inconvenient questions. Hoping to lead him off her trail, Lily decides to keep her enemy close, but as their attraction grows into something much deeper, Lily's plans start to unravel. Because Daniel is set on finding the murderer—and Lily plans to get away with it—no matter what.
