Rurik: A Royal Dragon Romance. Brothers of Ash and Fire, #3

The huntress becomes the hunted. Charlotte MacQueen is tired of being told what to do. Stay in school. Don't hunt dragons. Don't have sex. Blah, blah, blah. Her overbearing brothers mean well, but they are seriously killing her social life. Life as chemist is about as exciting as watching water boil, so for one night, Charlotte is going to walk on the wild side. And to top it off, she's going to bag her own dragon and show her brothers once and for all she's more than their baby sister.
She just never expected to fall for a dragon. The player gets played. Rurik Barinov's days are spent defending his family's homeland from rival dragon clans. His nights, deliciously spent indulging in carnal pleasures of the flesh, a hoard of women available at the nod of his head. Drinking, dancing, and sex keep his hot-blooded warrior dragon in check-but just barely. The last thing he wanted was love.until she walked in the club- living, breathing sex poured into a tight, red dress.
With one kiss, and one look into her vulnerable eyes, he's lost. Now his impenetrable heart has been, well, penetrated, making him vulnerable. And the worst part? She's the little sister to his sworn enemies. When Charlotte becomes a pawn against Rurik in a ruthless dragon clan-war, he'll have to work with her brothers (yes, the dragon hunters) to save her. Unless they kill him first.
