From the author of It Waits in the Forest comes Sarah Dass’s next stand-alone supernatural thriller—a lush and evocative tale of the rot that grows at the heart of even the most beautiful places. Perfect for fans of Angeline Boulley and Tiffany D. Jackson!

All Maya Woods wants is to reunite her three best friends, Pearl, Erica, and Lystra, for one last epic boat trip to the islands around their Caribbean home before they all graduate from high school. But the girls are forced to make an emergency landing on Annatto—an island avoided by locals and tourists alike because of the rumors of monsters and shadows that lurk in its depths—and their yearly tradition descends into darkness as Erica turns up dead and the girls are forced to leave her body behind.

Their tight-knit community is sent into a spiral of grief and suspicion, and Maya and her friends are at a loss to understand what happened: was it simply an accident or is there truth to the rumors about Annatto?

And while the community rejoices when Erica mysteriously returns alive and well a week later, Maya can’t seem to let go of her questions. What did they see that night? And who—or what—has Erica returned as? As old arguments and new betrayals rise to the surface, Maya and her friends can feel the shadows closing in on them. Something is lurking in the night, and they must be ready to face it.

Drawing from the darkest corners of Caribbean mythology, acclaimed author Sarah Dass delivers a supernatural thriller blends cultural nuance with monsters that go bump in the night, giving long-time Rick Riordan Presents fans the kind of story that will root into their hearts and awaken never their deepest fears.
