Months after Abigail and her friends thwarted a dark magic ritual that threatened to destroy Younwity Institute, new dangers and long-buried secrets bubble to the surface. As autumn turns to winter, a mysterious, rune-dotted fissure has appeared on the school grounds, and no one from the Coven is able to seal it—no matter how powerful their magic is. Even worse, it’s believed this fissure is the source of dangerous tremors that continue to rip through the grounds, threatening the Institute’s very foundation. Abigail is certain this is all her fault and hatches a plan to seal the fissure herself, but when her ritual goes sideways, she awakens a long-dormant entity hellbent on revenge. To put things right, Abigail will need to unearth the true history of Younwity Institute and, just maybe, unravel the secrets of her own forgotten past along the way.
