His Burning Desire by Valerie Twombly

Dragon shifter Connor O’Rourke loves his life as a firefighter, but one thing remains missing. His mate. She left him high and dry with only a note and the memory of her kiss. When several mysterious arsons are committed in Dallas, the shifter is called in to investigate and discovers Jenna working at the local firehouse. Jenna Dunne was betrothed to the strong and sexy shifter at birth. While there was no doubt she wanted to be his mate, she is a halfling and might never bear him the children he desires. With his species dwindling and the barbaric rules their society enforces, she knows Connor could toss her aside for another woman. There is only one thing she can do to save her heart. Run. Connor has two choices, free his mate from the bond that was started long ago or fight for the woman he loves. With an arsonist on the loose, Jenna’s life is in danger, and their chance for happiness may come too late. THIS BOOK IS A STAND ALONE STORY.
