Romance Readers Reading Challenges discussion

Hi guys, I am looking for a book where the heroine gets cheated on my her husband with her step sister I think or sister. She divorces him and when she goes to her attorney she sees a hot movie star who she has a crush on and she falls and embarrasses her self and the hero helps her as she drops everything out of her bag. Later on in the book the hero signs with her step father company and her overhears the stepfather shouting at the heroine and defends her.

It sounds like by Harper Sloan
