Would you recognize a real scream on Halloween? That’s the question haunting Norah Lewis. She can’t shake the guilt that’s stalked her since the night her brother was murdered. She heard—and ignored—his last screams. Just like everyone else at the Thicket, a haunted attraction in tiny Declo, Idaho. But as Halloween approaches, Norah’s personal tragedy is overshadowed by a media circus. Parents’ groups and PTAs lobby for a shutdown while thrill seekers far and wide clamor for a chance to visit the notorious haunted attraction. Many of Norah’s classmates eagerly plan a visit. And, reluctantly, so does Norah, who is driven to retrace her brother’s last steps. But the man in the grainy security footage whose masked face is plastered across the news hasn’t chosen the Thicket at random. And, like Norah, he’s planning a return visit.
