Moored among the tranquil islands off Thailand's coat, the Aurelia's passengers are completely unaware of the danger lurking just out of sight.

Patricia would happily remain oblivious, too, but that's not really how her life works. So when a couple report their teenage kids have gone missing, the ship's detective swings into action.

Had she glimpsed the terror awaiting her, she might have thought twice.

There's a secret to uncover, the kind people will kill to protect, and she must expose it if there is any hope of rescuing the missing teenagers.

More alone than usual, running for her life, and short on plans, things don’t look like they can get much worse. Which is when she sees the Aurelia sailing into the sunset without her on board.

Get ready for mystery and mayhem!
