Love Spell - Smoky Mountain Dragons, #1

My grandmother promised me to a hot, cursed dragon who happens to be her mortal enemy. Why does she want me to spend the rest of my life with a man she calls 'lizard breath'?She's an enchantress and she cast a love spell over Tyson Drake fifty years ago. It failed pretty spectacularly, and he's been trapped in his human form ever since. But she's convinced I can change things. That the magic she's been teaching me about is enough to make the spell come true.
Now Tyson's willing to give Gran's magic one more try and take a chance on me. I can't stop thinking about him, but will becoming Tyson's mate be enough to make him finally shift into his dragon form, or will my magic be the death of him?
