Vermilion Stars by R. O’Leary

Admittedly, taking the bounty was a bad idea… but how was she supposed to know the big bad wolf had a thing for humans?
Too small, too female, too human. As one of the only bounty hunters in the galaxy, Lena has heard it all before. When a bounty large enough to change her life comes along, she can’t help but leap at the opportunity. There’s only one problem… the wolf.
The Lupari wolves are the boogeymen of the universe, and tangling with one the alien monsters is certain death. But with that kind of money, who needs common sense anyway? Lena’s not one of the best in the business for nothing—but trapping the handsome bastard might just be more than she bargained for.
Shaw didn’t escape from an intergalactic prison to be put in chains by a trigger-happy female with bad taste in body armor, much less to find himself attracted to her. It’s hard to focus on making a break for freedom when all he can think about is the determined bounty hunter’s leather-clad curves. So much for his carefully laid plans.
When the unlikely pair find themselves stranded and hunted by half the universe, they will have no choice but to trust each other or die trying… if they can survive the attraction burning between them first.
