In her YA debut, Howe blends a modern medical mystery with the historical Salem Witch panic. Colleen Rowley and her friends attend St. Joan's Academy, a private high school in Danvers, Massachusetts. After one of the students has a strange seizure during class, her mystery illness quickly spreads throughout the school. Soon the media descends on St. Joan's, as everyone scrambles to find something, or someone, to blame. Colleen, who’s been reading The Crucible, discovers that Danvers was once Salem Village, where another group of girls suffered from a similar epidemic three centuries ago.
