“An eerie and gripping tale of suspense….A triumph.”
—Boston Globe

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." But their penchant for acts of meaningful vandalism and elaborate, often dangerous pranks results in Suz's death in the woods of Vermont—a tragedy the surviving Dismantlers decide to cover up.

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?

Full of white-knuckle tension with deeply human characters caught in circumstances beyond their control, Jennifer McMahon's enthralling story proves that she is a master at weaving the fear of the supernatural with the stark realities of life.

“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.

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.

“Don’t Breathe a Word is a haunting page-turner that kept me up, spine shivering and enthralled, way past my bedtime.”
—Joshilyn Jackson, author of Never Have I Ever

On a soft summer night in Vermont, twelve-year-old Lisa went into the woods behind her house and never came out again. Before she disappeared, she told her little brother, Sam, about a door that led to a magical place where she would meet the King of the Fairies and become his queen.

Fifteen years later, Phoebe is in love with Sam, a practical, sensible man who doesn't fear the dark and doesn't have bad dreams—who, in fact, helps Phoebe ignore her own. But suddenly the couple is faced with a series of eerie, unexplained occurrences that challenge Sam's hardheaded, realistic view of the world. As they question their reality, a terrible promise Sam made years ago is revealed—a promise that could destroy them all.

“Jennifer McMahon never flinches and never fails to surprise…as [she] weaves a young couple into a perverse fairyland where Rosemary’s Baby could be at home.”
