More than sixty years after the Battle of Hogwarts, the wizarding world is still feeling the effects of Voldemort's near-takeover. Strict laws have passed prosecuting those who practice the Dark arts and anything even tangentially related. Hogwarts professors are not allowed to even discuss dark magic, the teaching of occlumency is forbidden, and there is an outright ban on legilmency. Knockturn Alley is now a historical district only, as the sale and even the possession of dark artifacts became illegal long ago.

In the last few years, a mysterious group, headed by Minister of Magic Carden Pembroke, attempted to buck this growing trend. But after his tragic death in November, the Wizengamot seized power, and that effectively crushed all organized dark wizard resistance. The Wizengamot's next targets? Vampires and werewolves. But at least one of those groups has a plan to strike back - a plan that could prove deadly for more than one innocent student.

In the spring of 2059, new and untested Hogwarts Headmistress Maz Cowan is contending with mysteriously disappearing students, reappearing friends, a werewolf student, paradoxical time-travellers and all the usual adolescent troublemakers. To keep the school open she must struggle against the forces of darkness, even as she struggles with her own losses, and the darkness from within her own soul.
