In 1998, a sixteen-year-old girl is found dead. She’s posed on a swing on her boarding school’s property, dressed all in white, with no known cause of death. Whispers and rumors swirl, with no answers. But there are a few who know what happened; there is one girl who will never forget.
One year earlier: a new student, Violet, steps on the campus of Elm Hollow Academy, an all-girl’s boarding school on the outskirts of a sleepy coastal town. Uncertain and desperate to fit in, she soon finds herself invited to an advanced study group with three other girls, led by her alluring and mysterious art teacher, Annabel.
There, they delve into the school’s long-buried grim history of the occult and of gruesome 17th century witch trials. Their teacher does her best to convince the girls that the classes are just history and mythology, but the more she tries to warn the girls off the topic of magic, the more they are drawn to it, and the possibility that they can harness that magic for themselves.
Violet quickly finds herself wrapped up in this heady new world of lawless power—except she is needled by the disappearance of a former member of the group. As her friends’ actions take a turn for the darker and spiral out of control, she begins to wonder who she can trust, all the while becoming more deeply entangled. How far will these young girls go to protect one another… or to destroy one another?
