Heartfire — B.J. McCall

The universe is vast, but finding a dragon on the auction block isn't a usual occurrence for hunter Daecon Kreass. When the magnificent dragon shifts into a stunning woman, she stirs his blood like never before, but Arara is Zyafayan aristocracy and Daecon must keep her at arm's length and return her safely to her royal family.

Arara has never forgotten the handsome vampire who saved her from captivity. Determined to find out if her feelings are true or that of a grateful victim, Arara changes her appearance and her name. She joins Vazan Shield and is partnered with Daecon in the new hostage rescue unit.

Despite her deception the flames of passion are quickly ignited. This time around she's determined to never let him go.
