Dark Fire by Cynthia Sax

What the Beast wants, the Beast gets.

Dare’s savage nature has made him an outcast among his kind. The silver-scaled Dracheon warrior can’t control his inner beast. It’s too strong. When his primitive instincts told him his destined mate was on Carinae E, he had no choice. He had to travel to the outlaw planet. There, he hoped to meet a female powerful enough to survive his Drache.

He finds Faylee, a delicate little human.

Faylee is the best thief on the planet. Everyone she encounters mistakes her for a young boy…except for a tall, shiny warrior from off-planet. When she gazes into Dare’s flame-filled eyes, he makes her feel, for the first time, like a desirable female. The fire-breathing male has her yearning for hot kisses, fierce embraces, and a future filled with love. She doesn’t realize mating with him might be the last thing she ever does.

Dare’s beast isn’t the only danger on the planet. An enemy from the past has returned and he’s determined to stop Dare and Faylee…permanently. They’ll need luck and the assistance of every warrior in the Refuge to stay alive.
