The Wind Rages: Elemental Academy, Book 4 (Unabridged‪)‬

After discovering the Inquisitor’s plot within the Academy, Tolan is offered a chance to go with his father and learn from the Draasin Lord. Doing so not only means turning against the Academy and everything he has come to know, but means the Inquisitors will succeed in their plan. 

When the Grand Master comes to him asking a dangerous favor, Tolan must make a choice that might bring him into direct contact with the Draasin Lord.

Everything he’s been taught about the elementals and the Draasin Lord is wrong. 

If he can stop Aela and the Inquisitors, he might be able to save the Academy, but the Draasin Lord has something else in mind for him.
