Magic is a part of everyday life, but necromancy is still feared. Sixteen-year-old Natalie Wright knows this better than anyone. As a rare female necromancer, she arrives at the Chicago Girls' Institute for Arcane Studies expecting prejudice and tough classes. She brings her undead cat Manfred along for comfort. She quickly bonds with a group of diverse and talented girls. But her normal school experience shatters when a ghost named Thomas appears in her dreams. He points her toward a hidden history tied to her own bloodline. Her grandfather was not just a dark magic user. He was the Ossuary King, the leader of a violent and fanatical cult. The cult is not entirely gone. They are hiding within the school walls, watching her every move. As the danger closes in on the academy, Natalie realizes she cannot run from her legacy. To protect the friends she has grown to love, she must embrace her terrifying magic and forge her own path-before the cult claims her for themselves.
