His Bride by Luna Kingsley

I hate myself for wanting her.
I’m furious when Kendra insists on joining my scouting mission. Humans are too weak and fragile for this planet. She’ll slow me down and put everyone at risk, but I can’t refuse. I have my orders.
Disaster strikes when we venture into the desert. With no hope of rescue, we rely on each other to survive.
Every time she laughs at my jokes, tends to my wounds, or tells me a story about Earth, my heart softens a little. She sleeps against my shoulder and I marvel at the softness of her skin and the silkiness of her hair. In my dreams, I take her to my bed and claim her night after night.
Then I do it for real.
What if the woman I’m supposed to hate is the love of my life?
