Silver Princess (Bk 1‪)‬

Rebecca's afternoon joyride goes terribly wrong when she's bucked off her dragonfly, Belle, and has to spend the night in the woods. The mysterious stranger she meets reluctantly offers to take her back to the castle, where circumstances force him to remain.

The more she learns about him, the more bewildered she becomes. He knows who is trying to dethrone her father and why. But how can she feel as she does about him when she isn't even sure she can trust him?
