The Demon Prince by Emma Hamm

When a demon gets a taste for his own subjects, only one woman will offer herself to stop him.

Gluttony has existed in the shadows for centuries. He’s consumed everything possible. Food, wine, magical substances, even the sweet kisses of maidens. But when he realizes the one thing he’s never consumed is a human itself, his kingdom spins into chaos.
Katherine lives in the shadows of her village. Injured as a child, she isn’t a suitable match for marriage. So instead, she dedicates herself to having some purpose in the town. Stitching people up after Gluttony has his way with them makes her realize that she could be more of a solution than a problem.
So she makes the trek up to his castle and offers him a deal he cannot refuse. Her blood, unlimited, if he will leave the rest of her town alone.
Though he’s never even considered such a deal, Gluttony finds himself obsessed with this new human pet. He cannot get her honey scent out of his nose, or the kindness of her touch out of his mind. And swiftly he realizes that she soothes an ache in his chest he had forgotten existed.
This little human has reminded him how lonely he is. And now he’ll do anything to keep her.

Book 3 in the Seven Deadly Demons series will follow Gluttony back to his kingdom hidden in the moors….
