Kelsey's summer should have been a paradise - a holiday on Beverly Island, complete with sun-drenched beaches and gorgeous lifeguards. But Kelsey's dream holiday quickly turns into a nightmare. It starts with the note from a girl who's missing. Then there's the crazy man in the lighthouse with his mysterious warnings. And there have been a number of suspicious drownings . . . At least she has the lifeguards around to protect her . . . Poor Kelsey. Someone forgot to tell her that lifeguards don't always like to save lives.
