Smarts in Space by Juniper Jaxx

Brooke:
Six months ago, I was abducted by slave traders and destined for a breeding program. I thought I was doomed, that I’d never be able to pay off my mom’s medical bills—until a big scary red alien rescued me. A big scary alien who dropped me off at Critter Daycare, kissed me senseless, and disappeared.
Now he’s back and I shouldn’t want him, but I do. But being with Xakhis won’t just get me fired and ruin his future—it’ll paint a target on my back from the planet’s two warring tribes. One night could be the end of us both, but I can’t deny my need for his big, scaly alien body.

Xakhis:
Ever since I saved the beautiful, curvy human from my brother’s clutches, I haven’t been able to stop thinking about her, and her sweet, sassy mouth.
But she’s off-limits. It’s hard enough for a half-breed like me to be accepted into Zo’tox society, and taking a human as my mate will mean throwing away any hope of acceptance. I promise myself one amazing night. Except I know that one night will never be enough, no matter how forbidden she is.
She’s my mate, and I won’t stop until she’s mine.
