For an experienced scuba diver like Sia, it was supposed to be like any other wreck dive. Take the tourists out. Explore the reef. Uncover the secrets locked in the sunken craft. But when a bioluminescent beast bursts up from below, it destroys Sia’s boat and kills dozens of her customers. Sia and a handful of survivors, including her seven-year-old brother, wash up on a deserted island with no sign of rescue in sight, and the only food they can find lies in the strange beast’s hunting ground.
But the island isn’t what it seems. A horrible déjà vu clings to everything. Haunted by her own mistakes and an inescapable dread, Sia’s best hope for finding answers may rest in the center of the island, at the bottom of a flooded sinkhole that only Sia has the skills to navigate. But if the creature lurking in the depths doesn’t swallow her and the other survivors, the secrets of a fractured reality within might.
“Lutz strikes the perfect balance of realistic and uncanny, and Sia’s dive sequences, in particular, are seriously spooky. While this type of thing has been done before, Lutz does it so darn well that readers won’t mind, and the choice to tell the story via Sia’s letters to her father adds poignance.” –Kirkus Reviews
