A vow. A risk. A dilemma. A murder.

Victoria believes she's cursed. Everyone she's ever loved has ended up dead. Bellany has promised her safety and seems like a friend, one Victoria would kill for. But Bellany is never what she seems, a master manipulator, she's always pulling invisible strings. Together they flee to Mexico, where Bellany has a plan to settle the score with the man who betrayed her.

Cory's built his new life around protecting his sister, Tasha. He wants nothing more than a quiet life on the beach for them both. But he senses danger immediately; he knows Bellany has found him. As his allies arrive, determined to finally stop her, old wounds reopen and tensions ignite.

When the group is lured aboard a luxury yacht, escape is impossible. Trapped in a sadistic game where survival demands blood, paranoia fractures every alliance and every choice comes with a body count.

Out at sea, there's nowhere to run.
