When an ivory envelope with gold embossing and a sprig of lavender inside appears on their doorstep, they believe. They believe the world has finally said "thank you." They believe that a private Mediterranean island, Michelin-starred dinners, and sunsets over turquoise waters aren't a trap, but a reward. The first two days are perfect. Leon laughs—truly laughs. For the first time in years, she doesn't flinch at his nightmares. The wine flows freely, jazz plays until midnight, and it feels as though a bright chapter in their lives has finally arrived. But on the third day, the girl from the CDC disappears. On the fourth—the NATO general. Satellite comms go dead. The helicopter leaves at midnight. The pier is set ablaze. And from subterranean levels that shouldn't even exist, something rises—something the world believed had been eradicated. Las Plagas. San Esperanza is no resort. It’s a laboratory. And they aren't guests. They are the control group in an experiment that can no longer be stopped. Seven rounds in the magazine. Forty kilometers to the mainland. Dozens of voices howling in the dark outside the window. And one hand you can never let go of—no matter what happens. Welcome to paradise. There is no way out.
