Rennyr by Veronica Scott

Rennyr was a genetically engineered senior soldier in his Badari Warrior pack until one day he woke up on a strange planet naked, disoriented and about to be sold into the gladiator arena for the rest of his life. Unscrupulous guards faked his death in the lab where he was created and sold him into slavery in the galaxy’s hinterlands. Kill or be killed is the rule in his new life and a Badari never gives up. He’ll fight to stay alive until the Badari goddess sees fit to decree his death and release him from the wretched existence.
Jaine Mitchel of the Sectors was on her way to an exciting research internship until pirates seized the spaceship on which she was a passenger and took her to feature in a gladiator ‘death match’ in the galactic hinterlands. She has no hope of surviving in the arena until a man she only glimpsed in passing breaks out of his cell and saves her life, declaring her to be his fated mate.
Given to Rennyr as his reward for winning the death match, Jaine must share a cell and a bed with the handsome, not human, gladiator and together they have to find a way to survive in this merciless world of violence and death. Their mutual attraction is off the charts. Falling in love is the easy part, finding a way to escape or even to remain together is the challenge. At any time their mutual owner could decide thumbs up or thumbs down on one or both of them, or sell them separately.
Their only hope is a mysterious gladiator master from offworld who may be coming to buy Rennyr. Will he take Jaine as well? Could Rennyr win freedom for them both if he does well enough in the arena?
Badari Warriors claim their mates for life and Rennyr has no intention of losing Jaine…
