In this riveting, atmospheric thriller that messes with your mind in the best way (Laini Taylor, New York Times bestselling author), three residents of a secluded, seemingly peaceful commune investigate the disappearances of two outsiders. Travis Wren has an unusual talent for locating missing people. Often hired by families as a last resort, he takes on the case of Maggie St. James - a well-known author of dark, macabre children's books - and is soon led to a place many believed to be only a legend. Called Pastoral, this reclusive community was founded in the 1970s by like-minded people searching for a simpler way of life. By all accounts, the commune shouldn't exist anymore and soon after Travis stumbles upon it... he disappears. Just like Maggie St. James. Years later, Theo, a lifelong member of Pastoral, discovers Travis's abandoned truck beyond the border of the community. No one is allowed in or out, not when there's a risk of bringing a disease - rot - into Pastoral. Unraveling the mystery of what happened reveals secrets that Theo, his wife, Calla, and her sister, Bee, keep from one another. Secrets that prove their perfect, isolated world isn't as safe as they believed - and that darkness takes many forms.
