Scholar Elin thinks she's been hired to translate a lost treaty. Instead, one signature ties her life to a rumored dragon lord-if one of them dies, the other burns with them.Lord Darius of the volcanic citadel expected obedience, not a furious, brilliant woman who finds the lethal clause he hid and demands new terms by firelight.Bound by old magic and a living mountain that could erupt at any moment, they must renegotiate not just an ancient contract, but the rules of power, trust, and desire. Each word they rewrite shifts the magic around them-and makes their bond more dangerous to break.As cracks spread through stone and politics, Elin and Darius walk a knife-edge between survival and annihilation, attraction and ruin. To save a world balanced on lava and dragonfire, they'll have to decide if they're willing to fall together...or burn alone.
