His Mate to Keep by Ivy Sparks

They plan on making me do what? And… with him?

I’m a space pirate, and that means I’m used to finding myself in some pretty hairy situations. But getting abducted and imprisoned inside a remote experimental lab? Yeah, I think this takes the cake.
Then there’s my neighbor in the cell next door, Xavier. Despite being a smoking hot alien, he’s a brooder with a pronounced contempt for pirates like me. But that distaste can’t hide the look in his eyes when I’m forced to shower in front of him.
Everything changes when our experimenters demand we breed for them. If we ever hope to escape, we’re going to have to play along. But what happens after that? Will Xavier and I return to the loner lives we both once knew?
Or will we discover an unshakable bond neither of us thought was possible?

His Mate to Keep is an alien sci-fi romance, from the Warriors of the Lost Planet series of standalone books. This novel features a spitfire heroine and the sexy alien warrior who seeks to possess her. No cheating, no cliffhangers, and a very happily ever after is guaranteed.
