Fire Girl: Goddess Rising by Juliann Whicker

Too hot to handle... Unless you're a dragon. Ember’s task should have been simple: convince a wayward half-dragon shifter to accept his heritage, then go home to her isolated community to marry the betrothed she hasn't met, a powerful dragon shifter who can handle her flames. Cole, the half dragon shifter in question has no intention of accepting his heritage even at the insistence of an incredibly hot, literally and figuratively, burner whose out of control flames seem to be exactly what his inner dragon wants most. As irrepressible force meets immovable object, Ember’s community soon sends people after her, but not to help. Cole soon discovers that the beautiful girl disrupting his intentionally indolent lifestyle is not what he, or she, thought she was. Can Cole resist his dragon’s need to protect her? Can his heart, and house, resist her heat for long? As for Ember, with her entire world falling apart around her, could Cole be just the dragon she needs?
