Alien Invader’s Prey by Calista Skye

Althea
He’s a giant alien who just invaded my colony on Mars. And then he hunted me down and put a collar around my neck.
Now he’s talking about selling me to the creepiest aliens I’ve ever seen.
Okay, so maybe I shot him first. But he’s too shimmering blue and too heart-stoppingly gorgeous to miss.
He’s an overbearing jerk with some kind of superiority complex.
And still he turns me on like nobody has ever done.
But now he wants to know my secret.
And that’s a secret that I’d rather die than tell him.

Brox
She shot me, and I must punish her for it.
She’s small and soft and has a defiant spark in her dark eyes. That is very dangerous for her. The galaxy can be ruthless to small, disobedient females.
I can, too. She tempts me with her scandalous shape. She brings out the worst in me.
But I also want her secret.
And I always get my way.
