Captain's Fury (Codex Alera, Book 4)

Two years after the Canim invasion, Captain Tavi of the First Aleran Legion discovers a threat far more dangerous than the Canim themselves—the force that drove them from their homeland.

Tavi believes an alliance with the Canim is the only way to survive, but his warnings are ignored. The Senate's new military commander seeks to destroy the Canim and their allies.

Now, Tavi faces an impossible task: forge an alliance with a hated enemy and defy the law to save his legion and the entire realm. Can he overcome ancient animosities and unite friend and foe against a common darkness, or will all be destroyed?
