It’s 1997. Violet is a new student at Elm Hollow Academy and desperate to fit in. Quiet, artistic, and unremarkable, when she is invited to an advanced study group by her alluring art teacher, she is at once terrified and delighted. There she meets Robin, Grace, and Alex - charismatic outsiders who invite her into their clique. But once the study sessions on the school’s history of seventeenth-century witchcraft and magic become more than just theory, Violet must decide what she’s prepared to do in order to stay popular.
