Codex Alera #1- Furies of Calderon [Butcher, Jim]

In the realm of Alera, where people bond with the furies--elementals of earth, air, fire, water, wood, and metal--15-year-old Tavi struggles with his lack of furycrafting. As 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.
