Vivvy Bouchet, daughter of a known psychic, was ten when she saved a boy’s life by making an impossible prediction. Now she’s an astrophysicist in Texas, devoted to science, but the boy she saved has become a cop who continues to believe she can see things no one else can. When he begs for help on the high-profile cold case of a kidnapped girl, Vivvy steps back into the ocean of voices that once nearly drowned her.

It was a case that gripped the nation. In December 2003, Luke Ryder, the stepfather of acclaimed filmmaker Guy Howard (then aged 10), was found dead in the garden of their suburban family home. Luke Ryder’s murder has never been solved. Guy Howard’s mother and two half-sisters were in the house at the time of the murder—but all swear they saw nothing. Despite a high-profile police investigation and endless media attention, no suspect was ever charged.

Aidan Thomas is a hard-working family man and a somewhat beloved figure in the small upstate New York town where he lives. He’s the kind of man who always lends a hand and has a good word for everyone. But Aidan has a dark secret he’s been keeping from everyone in town and those closest to him. He’s a kidnapper and serial killer. Aidan has murdered eight women and there’s a ninth he has earmarked for death: Rachel, imprisoned in a backyard shed, fearing for her life.

Summer is coming to a close on the East End of Long Island, and Alex is no longer welcome. A misstep at a dinner party, and the older man she’s been staying with dismisses her with a ride to the train station and a ticket back to the city. With few resources and a waterlogged phone, but gifted with an ability to navigate the desires of others, Alex stays on Long Island and drifts like a ghost through the hedged lanes, gated driveways, and sun-blasted dunes of a rarefied world that is, at first, closed to her.

A successful film professor and podcaster, Bodie Kane is content to forget her past—the family tragedy that marred her adolescence, her four largely miserable years at a New Hampshire boarding school, and the murder of her former roommate, Thalia Keith, in the spring of their senior year. Though the circumstances surrounding Thalia’s death and the conviction of the school’s athletic trainer, Omar Evans, are hotly debated online, Bodie prefers—needs—to let sleeping dogs lie.

Lee Gulliver never thought she’d find herself living on the streets—no one ever does—but when her restaurant fails, and she falls deeper into debt, she leaves her old life behind with nothing but her clothes and her Toyota Corolla. In Seattle, she parks in a secluded spot by the beach to lay low and plan her next move—until early one morning, she sees a sobbing woman throw herself into the ocean. Lee hauls the woman back to the surface, but instead of appreciation, she is met with fury.

Emma Carpenter lives in isolation with her golden retriever Laika, house-sitting an old beachfront home on the rainy Washington coast. Her only human contact is her enigmatic old neighbor, Deek, and (via text) the house’s owner, Jules. One day, she reads a poorly written—but gruesome—horror novel by the author H. G. Kane, and posts a one-star review that drags her into an online argument with none other than the author himself. Soon after, disturbing incidents start to occur at night.

Grace Holloway keeps to herself. Since narrowly escaping death at the hands of the man who kidnapped her, she’s thrown herself into the small inn she runs in Rock Harbor, Maine. It’s quiet, quaint and, in the off-season, completely isolated—the perfect place for Grace to keep her own secrets. But Grace isn’t the only one with something to hide, and Rock Harbor isn’t just a sleepy vacation town. Someone is taking young women—girls who look an awful lot like Grace did when she was kidnapped so many years ago.
