Royally Dragon Bound — Melissa Haag

Don't pet my dragon. He bites. I'm no princess, and Vidar is no prince. Yet, I was no less royally screwed the minute I asked him for help. Turns out, granting that kind of favor makes us dragon bound, and that's something I did not sign up for.
 For the last year and a half, Kelsey and her sister have been on the run from a fate worse than death. Unfortunately, their hard-won safety in a town filled with mythical creatures shatters when the world starts shaking and their past catches up to them. 
In a desperate moment, Kelsey asks her angry and hot-as-sin neighbor for help. If only she'd known dragons protect for life. What the heck is she supposed to do with a surly dragon?
