Promise Not to Tell »

Jennifer McMahon is the author of Island of Lost Girls and Promise Not to Tell. She lives in Vermont with her partner, Drea, and their daughter, Zella.

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.

Part mystery-thriller and part ghost story, McMahon's well-paced debut alternates smoothly between past and present. In the fall of 2002, 41-year-old Kate Cypher, a divorced Seattle school nurse, returns to New Hope, the decaying Vermont hippie commune where she grew up, to visit her elderly mother, Jean, who's suffering from Alzheimer's. Kate has avoided New Hope since the grizzly, unsolved murder of her fifth-grade friend, Del Griswold, 31 years earlier. Kate fears she betrayed Del, a free-spirited farm girl. Did her betrayal cause Del's death? Who killed Del? Another local girl is murdered in a similar manner at the time of Kate's return. Could the killer be loose again? Meanwhile, Jean appears to be possessed with Del's spirit and may have the answers to these questions. As Kate investigates, she learns stunning truths about many events and people from her youth. McMahon does a particularly good job of portraying the cruelty of school children. (Apr.)
