The Gunpowder Regent

Trapped in the body of a disgraced nobleman's son, a modern soul awakens to a dying empire. Beset by enemies from within his own family and beyond, his only path to survival lies in the future knowledge he possesses. He will introduce revolutionary technologies to the battlefield, build a commercial empire that can challenge the state, and master the art of political warfare in a court torn between a reformist emperor and a shadowy retired monarch. Every victory earns him power and prestige, but also the deadly suspicion of the throne. When a long-buried secret about his true identity is revealed, he is thrust into the heart of the succession crisis, forced to decide whether to save the dynasty or remake it in his own image.
