One night. One secret. One girl who never came back.

The island welcomed four wealthy teenagers that week. By midnight, only three remained.

Seventeen-year-old Lexi and her rich friends arrive at an adults-only resort in Turks and Caicos, determined to escape their parents—and indulge in sun, sand, and wild nights.

But when a playful flirtation at a foam party goes too far, Lexi flees back to her room, certain she’s being followed.

Moments later, she vanishes into the darkness of the beach without a trace.

Local authorities dismiss her disappearance as teenage drama. But vacationing FBI agent Eva Rae Thomas can’t ignore the chilling details: surveillance footage featuring a notorious millionaire playboy, desperate denials that sound a little too sincere, and a group of privileged friends whose stories don’t quite match.

As turquoise waters conceal dark secrets, Eva Rae races to uncover whether Lexi fell prey to a predator—or to something far more personal.
