Books with title Academ's Fury: Codex Alera, Book 2

For 1,000 years, the people of Alera have united against the aggressive and threatening races that inhabit the world, using their unique bond with the Furies - elementals of earth, air, fire, water, and metal. But now, the unity of the Alerians hangs in precarious balance. The first lord of Alera has fallen in his efforts to protect his people from the vicious attacks of their enemies. Now, the fate of the Alerians lies in the hands of Tavi, a young man who must use all of his courage and resourcefulness to save his people.

The power-hungry High Lord of Kalare has launched a rebellion against the aging First Lord, Gaius Sextus, who with the loyal forces of Alera must fight beside the unlikeliest of allies - the equally contentious High Lord of Aquitaine. Meanwhile, young Tavi of Calderon joins a newly formed legion under an assumed name even as the ruthless Kalare unites with the Canim, bestial enemies of the realm whose vast numbers spell certain doom for Alera. When treachery from within destroys the army's command structure, Tavi finds himself leading an inexperienced, poorly equipped legion - the only force standing between the Canim horde and the war-torn realm.
