Compass (en Inglés) - Dale Hickman

At the Scholae, cadets are forged into officers, warriors, and future leaders of the most powerful military in the galaxy.

Asher Lockhart fits that world too well: brilliant, reckless, and powerful enough to make the wrong people nervous. Then the cracks start showing.

A friend's hidden past. A rival family with too much influence. An army invading a friendly planet. A princess who knows who she is and risks everything. And a kingdom is drifting toward a conflict that could swallow legacies whole.

Asher has spent his life learning how to fight. But fighting won't be enough when the real battle is over who gets to shape the future of Cassoria-and who gets sacrificed to build it.
