​Rowen Locke has won the battle. But from the shadows comes an ancient enemy--a calculating and merciless foe who has been waiting centuries for the chance to strike. Despite all he has already suffered and sacrificed, Rowen finds himself mired in a war bigger and more terrible than anything he could have imagined.

The world’s only hope lies in Knightswrath, whose hard-won powers he has only begun to understand, let alone control. Calling upon unlikely new allies, Rowen must raise an army to defeat the vengeful Dragonkin before everything he loves becomes a smoldering ruin.
