Academ's Fury - Jim Butcher - paperback

The Codex Alera series, book 2 of 6, completed series

For centuries, elemental powers have protected Alera from invasion, but the gravest threat might be closer to home. 

Tavi is struggling with a dangerous deception. He's trying to maintain the illusion of being a student whilst secretly training to be one of the First Lord's spies, a precarious game. And as he hasn't yet learned to manipulate the elements, he is particularly  vulnerable. 

In the country a large, a palpable sense of menace has exploded into violence on two fronts. An attack on the First Lord's life could lead to a bloody civil war. And in the Calderon Valley, the Marat threat is overshadowed by an infinitely greater problem. So now is the time for Tavi to harness his powers, as Alera's future is bleak indeed. 

Irene's notes: Jim Butcher is best known for his urban fantasy series, the Dresden Files. This is Jim's epic fantasy series, the series consists of six books, first book being Furies Calderon.
