Alien Warrior Unleashed by Ava Ross

Forced to compete in a deadly game, a tortured alien hero will do everything to protect his fated mate.

As a child, I was stolen by the lord of my planet’s invaders. He brought me to the chamber, where he held others he’d also taken. Through the years, me and my new brothers were twisted into hardened beasts, each with a unique ability that shouldn’t exist outside of myth. We’re monsters. Any female who gazes upon us will run.
Now we’ve been entered into the Galaxy Games. Each landscape contains a series of deadly pitfalls, shifting goalposts, and an elusive final destination. It’s my chance to break free.
But I’m paired with a delectable Earth female who makes me see color for the very first time, proving she’s my fated mate.
I’ll finish this Game. I’ll free my brothers. And I’ll claim the Earthling female as my prize.
