Chloe’s sister was married to Simon. The sister was not into “things” that Simon was, aka BDSM. So, she filed for divorce. She told Chloe everything and she was intrigued. More than that, she had always had a crush on Simon.
She didn’t go immediately, obviously, and the story has some twists and turns, but it was a great read. The perfect amount of drama, and wonderfully written scenes.
