From international bestselling author Karen Hamilton comes another pulse-pounding domestic thriller set against a lush, tropical backdrop as a woman fleeing her past as a con artist finds herself trapped aboard a cruise ship with someone who not only knows about that past, but will stop at nothing to get revenge.

It's an offer she can't refuse...and might not survive.

Charlotte has an unsavory past, but she's on the straight and narrow these days. She was so young then--she married the wrong man, falling for Sam's sweet-talking charm and charisma, and got caught up in his con artist games.

If only she'd left him before things went too far.

Now Sam is missing. But before he disappeared, he left urgent, cryptic messages about someone threatening him--someone who has been threatening Charlotte, too.
So Charlotte takes a job as a personal assistant for an engagement party aboard a private luxury cruise ship, the Cleobella, to get far away from anyone who means her harm.

But as the Cleobella sails through its glittering destinations, increasingly sinister events haunt the guests, and the turquoise waves and sun-drenched beaches give way to something darker. Someone knows what Charlotte did. Is it the blushing bride? The seemingly placid mother-in-law? Or the mysterious heiress?

Someone knows, and someone wants revenge--before the ship reaches its final port.
