Cole by Kathi S. Barton

Cole was the last of the unmated dragons. He was pretty sure one of the injured twins Rylie and Ryan, was his mate, but which one it was, was a mystery. Identical, they were both beautiful beyond compare, but their injuries ran deep. He would make sure they were both healed and protected, but some things could only be healed by love. Trust had to be earned, and trust was the one thing his new mate was having the most trouble with.
