After discovering the true identity of her mother, Sorceline finds herself tangled up in more mysteries and tests than ever before. With the departure of Archibald Balzar, she and the other students find themselves left in the care of Vorn, an entity at the center of their troubles who doesn't seem to share their concern for magical beasts.

Sorceline must find a way to free her father and save her mother from Vorn, but as she investigates, the creatures of the island face a new threat. While her friends look for treatments to puzzling injuries and Sorceline investigates, they'll soon find themselves the target of a mystical predator that threatens to destroy the island sanctuary for good.
