The Outcast Orc by Jordan Castillo Price

Being scooped up by slavers seemed like the worst thing that could happen to me. Then I was bought by a massive green orc.
I used to be the most sought-after horse trainer in the noble houses. But reputation is a fragile thing. One indiscretion made public, and suddenly those same nobles who’d praised my skill couldn’t shut their doors fast enough. I thought leaving the city would give me a fresh start. Instead, it landed me in chains.
Now I belong to Marok. Even to an outsider like me, he stands out among his kind—and not just because he’s the most imposing beast I’ve ever seen. The weight of the silence that follows him speaks of old wounds and deeper stories. And though he towers over everyone here, his own people look right through him.
In a world where humans are property and orcs are masters, I should be terrified. But I’ve never been good at knowing my place – and neither, it seems, has he.
When humans from the civilized lands find themselves claimed by orcs of the fearsome Red Hand clan, passion ignites. These stories weave together clan politics, ancient prophecies, and dangerous adversaries with slow-burn romance. The series follows unlikely heroes as they navigate treachery, cultural clashes, and unexpected attraction in a richly detailed world where survival depends on finding common ground.
