Heroes of the Empire: Book 1: The Cavalier - Chris Wraight

She calls the Empire home. He pledges to bring its downfall.

Death is Velamir's close acquaintance. As a student in the Chishman academy, he cannot escape the brutal war. When he's sent on a mission with three fellow academy cadets, Velamir returns to the Empire, the land of his birth. Calamity befalls the group as they trek through enemy territory, and Velamir learns a part of his past that makes the mission far more personal. Burdened with the deaths of the unavenged and the chance of losing his own life, Velamir must decide if revenge is worth the cost.

Natassa knows her role well: The silent and obedient girl. The one who looks away from the torture her father, the emperor, inflicts on the Empire's inhabitants. The princess. But she's a shackled prisoner, and somewhere under the mask is a spark of rebellion. When she learns of her father's intention to marry her to a man she loathes, Natassa crafts a risky plan of her own—one dangerous enough to get her killed.

Two searching hearts. Two perilous paths. Velamir must find the courage to face his past and Natassa must find the strength to face herself before the war consumes them both.
