George. Xavier's Hatchlings, #4

Imp had been alone in this world for so long she had forgotten what she was. It only took a little nudge from Winnie for her memory to come flooding back. She was a powerful earth fae and one of only three of her kind. She missed her siblings terribly, but it was too dangerous for the world for them to be in the same place. Imp was tired of being alone. As soon as Hudson Manning realized who Imp was, the rest of the Mannings knew as well.
Imp had created the first dragons. Cooper, the king of dragons, wanted to do something, anything, to repay her. Imp, however, didn't want to hear any more about it and was getting pissy when he wouldn't let the subject drop. George knew almost immediately that Imp was his mate, but convincing the stubborn woman would take a little work. When the two come together, their combined magic will be more powerful than any of them could ever imagine..
