“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.

A stunning and chilling thriller from the author of the New York Times bestseller Island of Lost Girls that further burnishes her reputation as "One of the brightest new stars of literary suspense" (Los Angeles Times online). 

When Henry, Tess, Winnie, and Suz form the Compassionate Dismantlers in college, the first rule of their manifesto is, "To understand the nature of a thing, it must be taken apart."

Nearly a decade later, Henry and Tess are desperate to forget, but their guilt isn't ready to let them go. When a mysterious Dismantler-style postcard drives a past prank victim to suicide, it sets off a chain of terrifying events that threatens to tear apart their world and engulf their inquisitive nine-year-old daughter, Emma. Is there someone who wants to reveal their secrets? Or is it possible Suz has found a way to enact revenge?

New York Times bestselling author Jennifer McMahon is back with a gut-wrenching mystery about an architect whose troubled mother has been found 25 years after being kidnapped—by a killer who is still on the loose

The summer of 1985 changed Reggie’s life. Thirteen, awkward, and without a father, she finds herself mixed up with her school’s outcasts—Charlie, the local detective’s son, and Tara, a goth kid who has a mental hold over Reggie and harbors a dark secret. That same summer a serial killer called Neptune begins kidnapping women. He leaves their severed hands on the police department steps and, five days later, displays their bodies around town. Just when Reggie needs her mother Vera—an ex-model with many “boyfriends” and a thirst for gin—the most, Vera’s hand is found on the steps. But after five days, there’s no body and Neptune disappears.

Now a successful architect who left her hometown behind after that horrific summer, Reggie doesn’t trust anyone and lives with few attachments. But when she gets a call from a homeless shelter saying that her mother has been found alive, Reggie must confront the ghosts of her past and find Neptune before he kills again.

With her signature style, Jennifer McMahon portrays the dark side of adolescent friendship and introduces characters who haunt the imagination, along with a disturbing web of secrets, betrayals, and murder.
