Eleven-year-old Ava O’Brien tells her parents a terrifying story: classmates blindfolded and led into a hidden basement, masked figures performing dark rituals, and a suffocating presence that still haunts her dreams. They want to believe it’s imagination, but as cracks spread through their small-town life, they realize Ava may be telling the truth—and evil is closer than they ever feared. 4.2 stars, 100+ ratings on Goodreads.
