The Alpha’s Son by Sam Crescent

After being away from the pack for seven years, Joe Johnson is back. He’s ready to learn from his father so he can take over as alpha one day. On the first night back, he meets up with friends, and catches the most unexpected scent. It was like the best vanilla frosting he’d ever smelled, and he is shocked and delighted to find it’s coming from Darcy Pine.
She is also fifteen years older than him, and even though loved by the pack, is considered boring.
Darcy is not mated. She has never been mated because she refuses to settle down with anyone but her true mate. After discovering the alpha’s son is her mate, she’s terrified. Joe is not taking no for an answer.
But Joe has a secret. He has never been with a woman. For as long as he could remember, he has had a crush on Darcy, and even when he was younger, he was obsessed with her.
Darcy has never been with a man, but when it comes to Joe, she cannot deny her attraction. Rather than tell anyone, they decide to keep their relationship a secret. They don’t want the pack to know.

However, when one of Joe’s friends insults her, Joe cannot control his need to protect her. They cannot keep their relationship a secret for much longer, but will the pack accept them?
