From the Wall Street Journal bestselling author of Constance comes a new supernatural thriller in which a hidden darkness is awakened, catalyzing a small town’s descent into nightmare territory.

Matthew FitzSimmons’s acclaimed novels Constance and Chance established him as one of today's most inventive suspense writers, and he now takes terror to a new level with this sweeping work of supernatural horror fusing small-town mystery and psychological dread into an unforgettable epic.

After the collapse of her marriage, Molly Donovan returns to her Pennsylvania hometown of Reese Hill with her teenage son, hoping to rebuild their lives. Instead, she becomes increasingly concerned for her newly retired father, who quickly becomes obsessed with restoring the antique radio she’d gifted to him. As the device returns to its former glory, respected townspeople, business owners, and lifelong neighbors begin changing in subtle but deeply unsettling ways, drawn toward an unseen force offering certainty, belonging, and purpose—all at the terrible cost of memory, identity, and free will. Now as growing violence spreads throughout Reese Hill, Molly realizes the greatest threat isn't some monster hiding in the shadows, but a community’s willingness to surrender itself to something ancient and unknowable. To save her family, and perhaps herself, Molly must confront a terrifying evil that has been waiting generations to be heard.
