Another school year begins at the Younwity Hidden Institute of Witchcraft, and Abigail knows that this is the year she needs to buckle down, grow up, and start taking her studies seriously. But everything is thrown off course when her mentee, Noreen, goes missing. Abby's classmates are quick to put Noreen's disappearance behind them-the Coven will find her, they say. They have it under control. But Abby can't let it go, and her search for answers leads her down a rabbit hole that uncovers more secrets than she can handle. As the mounting evidence steers her toward the off-limits woods that surround the academy, Abby begins to see that Noreen's disappearance has a lot in common with another girl who went missing, all those years ago.
