For three thousand years, an ancient dragon god has protected the borders of the Sheltered Lands. In return, he makes only one demand: every one hundred years, the mortal ruler must send their heir to serve as his consort…for as long as they can survive.

Sachielle of House Roquebarre is the thirty-first consort to be sacrificed to the monster who guards the mountain passes. She is young, beautiful—and she has three secrets.

First: she’s a disposable orphan trained in seduction.

Second: her handmaid, Zanya, is an assassin and the only person she has ever loved.

Third—and most dangerous: she’s cursed. Sachi and Zanya have five weeks to murder the Dragon in his bed. If they fail, the mortal king’s curse will steal not just Sachi’s life, but her very soul.

The Dragon has only one secret: he is nothing like what they have been told. And he will do whatever it takes to possess them both.
