I Married A Minotaur by Regine Abel

Tiny, sassy, but oh so fierce

Rihanna is condemned to a twenty-year sentence on the most savage prison planet in the sector for a crime she didn’t commit. On the day of her transfer, she’s offered a deal to commute her sentence: an arranged marriage with a grumpy orc-minotaur who has muscles for days, devilish red eyes, and an insufferably smart mouth. Despite his species’ reputation for being violent brutes, Rihanna soon finds herself drawn to the gentle giant that lurks beneath his terrifying appearance.

Fearsome, savage, and yet so fluffy

When the agency informs Zatruk he’s been matched, the last thing he expects is for his mate to be such a tiny human. With his people rapidly entering blood rage, and the looming threat of war, he needs a queen to stand by his side as he strives to save his people, not a delicate flower. But he soon discovers that behind her fragile appearance, his little female hides a fierce and dauntless soul, with a sassy attitude that stirs him in unexpected ways.
With time running out, will Rihanna be the blessing he needs to achieve the peace his people desperately desire, or will they self-destruct?
