Claiming Their Mate by Kallista Dane

CAPTURED. ENSLAVED. DELTA THOUGHT HER LIFE WAS OVER…
UNTIL SHE WAS GIVEN FOR A NIGHT TO DOMINANT ALIEN TWINS WHO MADE HER FEEL MORE ALIVE THAN SHE’D EVER FELT BEFORE.

Zandyr and Zhynn are Tharan Warriors, sent to the desert planet of Borvaan. Their mission: uncover the barbarian ruler’s plan to wage war on neighboring worlds – and rescue the human female sold to his harem.
Delta Greystone served as First Mate on the Earther ship Luna and the Tharans have been ordered to find and free her. They’ve been warned the pheromones of a human female will stir their gyron, awakening a savage need to dominate her and claim her as their mate. Together, as is the Tharan way.

Back on Earth, sex with her ex-fiancee was just one more thing for Delta to tick off her to-do list. But the hot alien twins awaken wicked desires she’s never had before and their thrilling mastery drives her wild.
When Delta finds out their spying has been discovered and their lives are in danger, she sets out across the burning sands to save the twins. Alone and on foot. Will Zandyr and Zhynn track her down in time – or will the merciless desert kill all three before the twins can claim her as their Tharan mate?
