Princeps' Fury — Jim Butcher

In the acclaimed Codex Alera novels, #1 New York. Times bestselling author Jim Butcher has created a fascinating world in which the people of Alera use their unique bonds with the elemental forces of nature for protection. But even nature may not be enough to stave off the coming storm...

Tavi of Calderon, now recognized as Princeps Gaius Octavian and heir to the Crown, has achieved a fragile alliance with Alera's oldest foes: the savage Canim. But when Tavi and his Legions guide the Canim to their lands, his worst fears are realized. The dreaded Vord -- the enemy of Aleran and Cane alike -- have laid waste to the Canim homeland. And the Alerans find themselves trapped alongside their former adversaries.

Meanwhile, war-torn Alera rebuilds while politicians and nobles vie for power. But from the south comes news: The Vord have come to Alera. For a thousand years, Alera and her furies have withstood every enemy and survived every foe.

The thousand years are over...
