Fighting for Mari by Katie Reus

He’s her brother’s best friend…
Corporate pilot Mari had a crush on Colin when she was a teenager, but that ended abruptly when she heard him say something awful about her. She’s ignored him ever since. Now that he’s out of the military and started a company similar to hers, they’re rivals and he’s trying to steal one of her clients—so she snags a land deal he wants.

And she’s hated him since she was seventeen…
When Colin Lockhart goes to confront Mari about blowing up his latest deal, he ends up saving her from an attacker. For some reason she seems to hate him and he’s never understood why—especially since she’s his walking, talking fantasy and their families are friends. With a smart mouth and lean curves, the badass woman is everything he’s ever wanted. When it’s clear someone wants her dead, he refuses to let her out of his sight—and they wind up stranded in the middle of nowhere with a plane that’s been sabotaged and killers hunting them. If they can’t put the past behind them and find a way to work together…they’ll die together.
