Alien's Primal Bond (Fated Mates of Apara Book 1)

The Ulkar are the stuff of nightmares, and they want to do much worse to Ellie than kill her. They want to breed her. Kula is sent to save her. He’s an Aparan warrior, the only race in the galaxy strong enough to fight the Ulkar. He swears to die protecting her, but there’s only one way to save her: The Ulkar will not breed with a woman who has already been claimed.
