A summer house holds dark secrets—and a terrifying evil—in the New York Times bestselling author’s “compelling gothic mystery” (Publishers Weekly). Lily Dale, New York, is a sleepy, summer resort. A population of psychics and mediums lives within its gates. It is also the place where Julia Garrity and Kristin Shuttleworth formed a fast friendship—one broken only by death. On Halloween night fifteen years ago, Kristin saw something in a house on Summer Street that would haunt her until the end of her days. Since then, Julia has watched both Kristin and her mother fall prey to whomever—or whatever—lurks there. Now Kristin’s blind six-year-old daughter, Dulcie, has come to live in Lily Dale—at that very house on Summer Street. Appointing herself protector, Julia is determined to coax the secrets of the house out into the light, to discover what the little girl “sees” roaming its halls . . . before the murderous force residing there claims them both.
