Patricia Campbell feels invisible. As a devoted wife and mother in 1990s suburban South Carolina, her days blur into an endless cycle of errands, dinner parties, and quiet domesticity — until her book club becomes the most exciting thing in her life. A group of women bonding over true crime novels and bottomless glasses of wine, reveling in stories of real-life monsters.

At an isolated boarding school bordered by a forest no one is allowed to enter, whispers become warnings, and warnings become obsession. Andrew spends his nights drawing grotesque creatures while his closest friend, Thomas, writes unsettling stories that seem to bleed into reality. But when the monsters from Andrew’s sketchbook begin appearing beyond the page, the line between imagination and nightmare starts to unravel.
