He’s her destiny, yet their love has been nothing but a series of disasters!
Amy’s younger sister has been a spoiled queen of high society, and Amy has supported her from the shadows. Amy’s willingness to give up on her own marriage to help her sister is linked to the secret reason her younger sister hardly says a word. Amy becomes even more vigilant than usual when she learns that ambitious Ben had plans to marry her sister just to get close to the famous sisters’ father. She’s heard rumors that this handsome man is the illegitimate son of a duke—he’s certainly quite the mystery. But whatever his circumstances, she won’t allow anyone to get close to her younger sister just to use her! Amy never imagined that she would become Ben’s prisoner!
