Smitten by the Dragon by Tully Belle

To stop more innocent people from being killed, Caran Rivers has been given the assignment to infiltrate and seduce one of the members of a mob organisation and take down the dragons they wield as weapons. If she’s successful, she’ll finally be accepted as a valued member of the group of women dragon assassins.

Ash Dragonspark and his brothers have just landed the job of the year and it’ll mean a hefty sum of money deposited into their pockets. He’s out to celebrate, and if that includes spending the night with the hot brunette at the bar, he’s fine with it. He’ll figure out what she’s hiding tomorrow.
