Flying Through Fire by Nina Croft

Winged monsters have been seen in the skies, and a pestilence follows in their wake, threatening the very survival of mankind. Only the crew of the Blood Hunter knows where they come from, and only one man has the power to send them back—Thorne, a human/dragon hybrid in possession of mental powers beyond comprehension.

Candace Decker doesn’t need anyone to look after her—she’s a badass werewolf more than capable of protecting herself and those she loves. All the same, she’s always been drawn to Thorne’s strength. In an uncertain world, he’s the one man who makes her feel safe. And what Candy wants, she usually gets.

But while Candy is tenacious, Thorne’s willpower has been honed over ten thousand years. He might want her, but the last thing he needs is an infatuation with a young, impetuous werewolf. Candy makes him lose control, and that could have disastrous consequences.
As the threat escalates and they become separated by time and space, Candy must find a way back to him, because while Thorne alone has the power to defeat the dragons, only together can they finally bring peace to the universe.
