In the 1950s, the Tower Motel—and its namesake Tower—were the shining attraction of tiny London, Vermont. Now it stands in disrepair, alive only in the memories of three women—Amy Slater, Piper, and Piper’s sister, Margot. They played there as girls until the day that their games uncovered something dark and sinister in the Slater family’s past, something that ruined their friendship with Amy forever.
As adults, Piper and Margot have done everything they can to move on; Piper lives in California, while Margot has devoted herself to studying local history and starting a family. Until, one day, Piper receives a panicked call from Margot: Amy and her family are dead, supposedly killed by Amy’s own hand. And before she died, Amy scrawled a message that the two sisters know was meant for them: “29 Rooms.”
Suddenly, Margot and Piper are forced to revisit that fateful summer, when they found a packed suitcase and haunting letters that once belonged to Sylvie Slater. Amy always claimed that her aunt had run away to Hollywood to live out her dream of becoming Hitchcock’s next blonde bombshell of a leading lady, but the truth is much more complicated. As they investigate, a new story unfolds, one of Sylvie and Rose, two sisters who lived at the motel during its heyday … and one who carries a secret that will haunt the generations to come.
