Primal Bond by Leo Rivers

Finn
I never asked to be a security payment. Yet here I am, handed over to Zanik, a seven foot tall brooding alien warrior who looks at me like I’m nothing but an annoyance.
He doesn’t want me, and I sure as hell don’t want him.
Zanik’s all razor-sharp angles and ice-cold glares, a total contrast to my warmth and wild impulses. We clash instantly.
But when past secrets rise up to claim me, he stands in their way.

Zanik
The last thing I needed was a human to look after. But now Finn is my problem. He’s reckless, impulsive — a liability I can’t afford.
Every careless grin, every too-bold touch, tears down the walls I’ve spent years building.
Somehow, he’s breaking through, and despite every defense, I find myself wanting him.
And when he needs defending from his dark past, I’m the only one in his corner.

Primal Bond is a dark scifi MM hurt-comfort romance featuring a grumpy alien warlord and the lost human thrown into his arms. It’s part of the Warlords of Vasz series, but can be read as a standalone.
