Jennifer McMahon is the author of six novels, including Promise Not to Tell and The Winter People. She graduated from Goddard College and studied poetry in the MFA Writing Program at Vermont College. Her latest book, The Night Sister: A Novel (Doubleday), is a suspenseful tale that probes the bond between sisters and the peril of keeping secrets. Once the thriving attraction of rural Vermont, the Tower Motel now stands in disrepair, alive only in the memories of Amy, Piper, and Piper’s kid sister, Margot. The three played there as girls until the day that their games uncovered something dark and twisted in the motel’s past, something that ruined their friendship forever. Now adult, Piper and Margot have tried to forget what they found that fateful summer, but their lives are upended when Piper receives a panicked midnight call from Margot, with news of a horrific crime for which Amy stands accused. As Margot and Piper investigate, a cleverly woven plot unfolds—revealing the story of Sylvie and Rose, two other sisters who lived at the motel during its 1950s heyday.
