Prince Ryuu hates his father, Emperor Midian. When he's forced to buy a slave, he defiantly chooses Drakon instead of a woman. Because he's determined to overthrow his father's empire, he can't afford to show vulnerability, but Drakon is more compelling than he'd anticipated. For an Arethuza warrior, affection is a weakness that can lead to death.

Drakon isn't really a slave—he's a black dragon, considered cursed by everyone. Despite his people's distrust, he will do anything to keep them safe, even submit to an Arethuza prince. He never expected to find love, and that complication could ruin his plans to sabotage the emperor's war campaign. Though Ryuu is his fated mate, their fledgling bond is a secret too dangerous for Drakon to reveal.

Will their duty tear them apart? Can honor prevail in a war that might be too violent for even the strongest dragon warrior?
