Written in the Stars by Leslie Chase

He might be the hottest guy in the galaxy, but I don’t need his help. Me and my alien cat are managing just fine.
Running a bookshop on a pirate space station isn’t easy, but Megan’s determined to keep smiling. A lot of hard work and a bit of luck will let her save up enough for a trip back to Earth—but then Drask walks into her shop. The grumpy alien mercenary is infuriating, arrogant, and hotter than molten steel. It wouldn’t be so bad if he wore more clothes—the blue-skinned alien’s muscles are a distraction Megan doesn’t need.
Talbrek Station is the perfect place to lie low, and that’s what Drask needs after a mission gone wrong. Finding a bookshop is an unexpected benefit, especially one run by the sexiest woman he’s ever seen. Exasperating, smart, and unwilling to back down from anything, Megan is everything Drask desires, wrapped up in a curvy package that won’t let him think straight.
When the local criminals threaten both Megan’s bookstore and her pet, Drask can’t stand aside. Not even if it drags them both into a gang war.
Written in the Stars was first published in the Pets in Space 7 anthology, though this version has minor changes.
