Do You Promise Not To Tell

“McMahon unfurls a whirlwind of suspense...Combining murder mystery and coming-of-age tale with supernatural elements, this taut novel is above all a reflection on the haunting power of memory.” –Entertainment Weekly A woman’s past and present collide in terrifying ways in this explosive debut by New York Times bestselling author Jennifer McMahon. Forty-one-year-old school nurse Kate Cypher has returned home to rural Vermont to care for her mother, who's afflicted with Alzheimer's. On the night she arrives, a young girl is murdered—a horrific crime that eerily mirrors another from Kate's childhood. Three decades earlier, her dirt-poor friend Del—shunned and derided by classmates as "Potato Girl"—was brutally slain. Del's killer was never found, while the victim has since achieved immortality in local legends and ghost stories. Now, as this new murder investigation draws Kate irresistibly in, her past and present collide in terrifying, unexpected ways. Because nothing is quite what it seems . . . and the grim specters of her youth are far from forgotten. More than just a murder mystery, Jennifer McMahon's extraordinary debut novel, Promise Not to Tell, is a story of friendship and family, devotion and betrayal—tautly written, deeply insightful, beautifully evocative, and utterly unforgettable.
