Some princes are born to rule. Others are born to kneel. Crown Prince Caelum Salutregui was raised to be humanity's perfect weapon—diplomatic, deadly, and utterly devoted to destroying the vampire empire. What he wasn't raised to know? He's vampire royalty himself. When the Ashan Federation offers him as a "peace tribute" to the very monsters he's sworn to hate, Caelum expects torture, death, maybe both. He doesn't expect General Velis Drayke—a sadist in uniform who sees right through his royal mask to the defiant soul beneath. But in the Crimson Dominion, submission is statecraft and pleasure is politics.
