The Escape by Sybur Phyre

Cylene
All I have to do is avoid being captured to win a million dollars. The challenge? Escape the hands of every alien warrior that gets dropped in the valley. They’ll have plenty of other women to snatch up. Easy peasy.
I’ve always been fast, athletic, but broke, and treated like I’m a source of free labor by my family. Well, my half-brother’s family. A million dollars could get me off of Earth and help me start my own business in the one thing I’m really good at—teaching women alien self-defense, like how to use their extra arms, tentacles, and horns to our advantage.
The women I’m stranded with on the alien planet outnumber the alien warriors, princes, and dignitaries by one. Only one of us can be free. Some of the women aren’t interested in the money, just a rich and powerful alien husband. I had to escape my family just to make it here. I know I’ve got a good chance at the prize money.

Vitus
I’ve finally let my best friend coerce me into signing up for the race. I tell myself I’m not stuck doing what my father pressured me to until his untimely death last year. Guilt made me finally commit.
If I’m unhappy with my selection, there’s a loophole to get me out of the commitment. If we want to trade brides with another male, we can simply negotiate at the Mingle Celebration. After taking control of my father’s army, I no longer tolerate being told what to do.
But when we land on the planet and I see a brunette climb the cliffs and disappear on the other side, something primal in me switches on. She is strong and would bear me strong warriors. It is honorable for Nytherans to continue their lineage with many offspring, but only with a capable mate.
I just have to catch her first.
