Mated to Her Bully by Sam Crescent

Lucas has been cruel to Mabel for as long as she can remember. So discovering he’s her mate is the cruelest twist of fate. There’s no way she’ll mate with him. Instead, she runs away to the city, hoping never to bond with him.
When Lucas’s dad interferes as the Alpha and tries to reunite the two, she attempts to sever all ties with Lucas and deny him as her mate. As the leader’s son, Lucas knows every loophole and demands the chance for reconciliation. He wasn’t good to her, but he wants the chance to make it right. She’s his mate, and against all odds, they are destined to be together.
Mabel has no choice but to follow the rules, and Lucas is a changed man. As a boy, he was a bully. Now he’s a man intent on winning his mate, and it isn’t a game. He wants Mabel by his side for the rest of their lives. Even if it means breaking down the wall she’s built around her heart.
