The Silent Partner (Without Rules #4‪)‬

A year and a half has passed since the car accident that left Mariss Red hospitalized, but she is healing and her life is back to normal. Well, as normal as possible for a woman who lost her husband and child, and for a man who didn’t believe in love.
Sebastian Boa now has a steady partner and two children to take care of. The four of them live in London and are working to shake free of the horrific events that brought them together. Christmas is on the horizon and the couple is looking forward to hosting both of their families and their friends for the holidays.
Mariss has a secret. She’s struggling with her dark side. Something happened when she was attacked, something that makes it hard to keep her fractured personality from surfacing. To make matters worse, someone from her past has decided to resurface and no one is ready to deal with it.
Sebastian knows Mariss is keeping something from him. He also knows that at any moment she could realize just what a huge mistake she made in loving a man like him. And a man like him knows it’s best to cut ties early, before he can get hurt or hurt her.
Problem is, he’s not that man anymore, and he’s not sure he wants to live without the woman who changed him so completely.
