"One of the finest literary craftsmen currently working is writing horror: Catriona Ward." --Olivie Blake, New York Times bestselling author From Catriona Ward, author of The Last House on Needless Street, comes a mind-bending tale of friendship and betrayal, and the impossibility of escaping your own story. In a cottage overlooking the windswept Maine coast, Wilder Harlow begins the last book he will ever write. It is the story of a sun-drenched summer of his youth and of the killer that stalked the small New England town. Of the terrible tragedy that forever bonded him with his friends Nat and Harper in unknowable ways. Of a horror that has followed them over the years. Wilder has returned to the town decades later in an attempt to recount that summer's events in his memoirs. But as he writes, Wilder begins to fear his grip on the truth is fading, and events in the manuscript start to chime eerily with the present. He's even started seeing a dark-haired woman down in the icy waters below the cottage, but nobody else can. No longer able to trust his own eyes, Wilder begins to fear that this will not only be his last book, but the last thing he ever does... "An alchemist of storytelling."--Chris Whitaker, New York Times bestselling author of We Begin At the End
