Alien Giant by Sue Mercury

A nine-foot-tall alien warrior just kidnapped me.
How’s your day going?
Diana is a survivor. It’s all she knows. But she has big plans once she escapes the dangerous outpost where she’s been stranded for the last ten years. Plans that involve buying a ship of her very own and traveling to a sparsely populated planet to live out the rest of her days in the sun. No more crowds, no more recirculated air, and no more cage fights. She certainly doesn’t plan on being “rescued” by a sexy alien giant with glowing green eyes who wants to make babies with her.
Kirn is enchanted by the fierce little human he’s stolen away from the outpost. Ah, what a beauty she is–and strong. She resists his advances at first, but he’s confident she will agree to become his mate soon. He’s a highly respected Vaxxlian warrior. How could she not want him? Mindful of his enormous size, he promises to be as gentle as possible when he finally mates with her. But as he’s about to discover, claiming a human female never goes as planned.
