While on "Couple's Therapy" Jon told his housemates that he spent two years writing his memory of what his marriage was like and his feelings about it because it's not libel or salacious so there really isn't much she can do about it, although she will likely sue him for defamation.
Kate had Robert Hoffman's tell-all book about her suppressed from publication two years ago and she will likely try to do the same with Jon's. However, Jon says that at this point he doesn't really care what Kate has to say. He wants to tell his side of things because nobody really knows what living with Kate was like. Jon thinks that people will want to know and have the right to know what the real Kate is about.
Without having any knowledge about what is going to be in the book, many have started re-questioning Kate's relationship with bodyguard/ manager Steve Neild. During their break-up, Jon publicly questioned the relationship as the lined were pretty blurred, but Kate denied having an affair with him.
