As a Black woman, Liz Rocher doesn't exactly have fond memories of Johnstown, Pennsylvania, a predominantly white town. But her best friend is getting married, so she braces herself for a weekend of awkward reunions. On the day of the wedding, the couple's daughter, Caroline, disappears. Liz notices a pattern: A summer night. A missing girl. A party in the woods. She's seen this before. Keisha Woodson, the only other Black girl in Liz's high school, walked into the woods and was later found with her chest cavity ripped open and her heart removed. With the evil in the forest creeping closer, Liz knows she must find Caroline or be entirely consumed by the darkness.
