My Mate by Sam Crescent

Dex Arlington is the Alpha’s son, and he will not allow anyone to hurt his mate. When he finds out she’s been beaten up by one of the pack wolves, he goes to settle the score. He doesn’t care that Casey hasn’t been able to change into a wolf. She belongs to him, and no one will hurt her, and anyone who tries will pay the price.
Casey Scott isn’t happy. Ever since she knew she was a wolf, all she has ever wanted was to transition. She wants to run out in the wild, beneath the full moon. Only, it never happens. Her wolf is not coming.
She doesn’t know how Dex can want her. Yet, nothing sends him away. He refuses to leave her alone. From the moment they first met as children, he said he knew they were meant to be mates.

But someone has a secret. They are closing in. Who would dare try to kill the Alpha’s son?
