Ethan Harris spent three years as Vivian's devoted doormat—until a shipwreck, when she kicked him off the lifeboat to die. Washed onto a remote island, he is flooded with past-life memories: he has been here before, where Vivian and the rich kid Zach tortured him as monster bait. But this time, he remembers every hidden danger and weapon.
He saves Sophia, a CEO who died first in his past life, and finds a hidden stun baton. When Vivian and Zach wash ashore, they order him around as usual—so he serves them poisoned coconuts, then digs up a buried submachine gun. Zach steals the now-useless stun baton, just as the monsters attack. With the battery dead, Ethan pulls out his real gun and saves them all.
Now he and Sophia feast in safety while Vivian and Zach rot. When the full monster army arrives, Ethan must choose who lives—and who pays.
