Since time immemorial, the Spires have sheltered humanity, towering for miles over the mist-shrouded surface of the world.

The savage Vord are on the march, and Gaius Octavian, first lord of Alera, must lead his legions to the Calderon Valley to stand against them--using all of his intelligence, ingenuity, and furycraft to save their world from eternal darkness.

"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 safely to their lands, his worst fears are realized.The dreaded Vord--the enemy of Aleran and Cane alike₇have spent the last three years laying waste to the Canim homeland."--Publisher's description.

In the Calderon Valley, a long--forgotten horror awakens and heads for the heart of Alera, while Tavi's closest relative, the newly appointed Steadholder Isana, faces at least two sets of assassins.
