How to Negotiate with a Nightmare

I have three problems: One: The hot guy I met in the bushes (don't ask) has magic so cold and dangerous it should come with a warning label. Two: My family's dragging me to a ball hosted by the Nightmare King—you know, the cruel monster who rules the dark half of town where the sun literally never rises. Three: Turns out Hot Bush Guy and Nightmare King are the same person. And when our magic touches? We make flowers. Which would be romantic if I wasn't supposed to be terrified of him. Eryx Nightshade has spent ten years alone in his castle, haunted by a voice in his head that demands blood and revenge. Until I walked into his spell and the voice went from "destroy everyone" to "she's pretty, don't mess this up." Now he's thrown a ball to find me. I'm trapped in pink tulle and sparkly sneakers. And every time we touch, our magic does things that shouldn't be possible. He thinks I'm his salvation. I think he might be mine. But I'm supposed to marry someone to save my family's dying magic, and he's got a revenge plot ten years in the making. Falling for the Nightmare King wasn't part of anyone's plan. Especially the nightmare's. Perfect for those who love: grumpy x sunshine; villain gets the girl; marriage of convenience; magical bond; morally gray (and slightly obsessed) hero; dangerous magic; fantasy romance with humor. How to Negotiate with a Nightmare is book three in the Seven Suitors for Seven Sisters series.
