Ruined: Revenge Wore A Collar

Suki never forgot the name Lincoln O'Brien. The man she believed walked away from her before she was even born. The man who chose his real family over her. So when she discovered his son Raymond was sitting three rows ahead of her in college, she didn't see a classmate. She saw an opportunity.
She collared him. Paraded him. Took his name, his money and his mind.
What she did to Raymond O'Brien, she did slowly. Deliberately. With a smile.
He called it the best thing that ever happened to him.
But revenge has a way of revealing things. And the truth about her own blood was waiting - patient and quiet - until she had nothing left to lose.
And by then, the collar was already around his neck.
