As Caleb and Duncan near the end of their summer holiday, their guardian and teacher Molly O'Toole is attacked by a horrific mutated scorpion, and it is the first of many. Students and instructors from other Army of the Light schools gather at Elemental for protection, but as events unfold, Professor Slimmerik and Caleb decide that something evil lurks within the walls of the school. To make things worse, it is possible that one of the people living at Elemental is not who they seem to be. Caleb must seek the aid of the one person he fears the most, the Guardian of the Forbidden Forest, the powerful goddess who destroys all who enter her protected woodland. He must brave terrible bloodthirsty creatures just to beg an audience. Without her help the students will be left at the mercy of the unknown evil and Elemental Academy might be doomed for all eternity. But is an alliance with the goddess worth suffering her wrath?
