Fire Line by Maggie Gates

Please note this is the Berkley Books Edition.

Lennon's number one rule is: Committing crimes is not a group project. Rule number two: Don't start fights. Finish them. And rule number three: Don't try to hustle a hustler. She knows she should have walked away and ignored that sweet-talking cowboy. Good things didn't happen to people like her. But that cowboy wouldn't leave her alone. And he should have known that if you can't stand the heat, it's better to get out of the kitchen.

Carson James knew the woman was trouble from the moment he laid eyes on her bruised knuckles in the bar. The last thing he expected was for her to show up on the ranch and bring that trouble to his front door. And he's discovering it's hard to maintain a grudge against a woman you find so attractive. He's always liked playing with fire, but apparently so does she. Only time will tell which of them is going to get burned.
