Ruin: Ardan K’ir by Celia Loren

Pria
Found abandoned as a young girl by a trader who immediately recognized her beauty and sold her into slavery, Pria was destined to spend the rest of her days at a notorious concubine training facility on the planet Arca, waiting to be bought.
She was taught many secrets of the sexual arts, how to be unwaveringly subservient, and above all, how to please her future masters.
But nothing could really have prepared Pria for the day of her purchase…to be the play thing for a savage gladiator they call “Ruin”.

Ruin
Growing up in the slums of a pirate planet, his prostitute mother left him an orphan to fend for himself. He fought to survive, often killing whoever stood in his way of food and resources.

Eventually conscripted into the rebel resistance, Ruin went on to become a great fighter pilot until his squadron was destroyed in battle and he was captured and sent to the Grange, a gladiatorial arena on the space city of Harcos.
His days are spent in the fighting pits, slaying rare and horrific beasts from far away galaxies. His nights are spent in the company of beautiful concubines.

There is no man or beast in the Vaxilius Galaxy that Ruin fears…but he may have finally met his match with the concubine waiting in his cell tonight.
