The Monster at the End of This Courtship by Edie Monte

What good is fate when your mate won’t look your way?

Omega Tuft has always wanted a mate. He’s craved someone to love and support him since he was a human changeling on Earth. Now that he’s a kobold/human hybrid, he understands this desire is hardwired into his genes. Too bad his new mate hasn’t gotten the message.
Axel had tried so hard to fit in on Earth. He’d had a fiancée, a steady job, and video games to keep him busy. Now, he’s an alpha adrift in one of those fantasy games with no way out and an omega who keeps calling him mate.
When Axel is returned to his plane of origin early, Tuft has only a brief courtship to convince him they’re meant to be together. If he fails, he’ll have to face the reality of living alone without any hope for love and hatchlings.
