One by One by Freida McFadden (Paperback)

Freida McFadden, the bestselling author of The Housemaid, crafts a claustrophobic thriller about a group trip that turns deadly. Far from help and cut off from the outside world, a small group of people begins to realize that someone among them is not who they seem.

As members of the group start disappearing one by one, fear and suspicion take hold, and old secrets come to light. Tightly plotted and packed with McFadden's trademark twists, this New York Times bestselling paperback is a page-turner for readers who love locked-room suspense and psychological thrillers.
