Furies of Calderon (Codex Alera)

In the realm of Alera, where people bond with the furies - elementals of earth, air, fire, water, and metal - 15-year-old Tavi struggles with his lack of furycrafting. But when his homeland erupts in chaos - when rebels war with loyalists and furies clash with furies - Tavi's simple courage will turn the tides of war.
