Billie and The Parent Plan is about a young girl who is upset with her mom for getting remarried. It turns out that her step-dad is old enough to be her grandfather and her 18-year-old step-sister is just another "adult" that Billie is not thrilled to all of a sudden be living with.
Her father was never around growing up and he wasn't discussed much in the book, but the entire premise of the book was about her having to get used to her new family and accepting these people into her home, which is something that many kids must deal with when (or if) their parents get remarried.
My son was not thrilled with this idea either. The thought of my getting married (someday) never crossed his mind and he was adamant about the fact that he was not OK with it. I wasn't going to argue with him or tell him that I was never going to get married but I have a feeling that talking about it now (as opposed to when - or if - that person comes along) will prepare him for it, if that day should ever come.
The book, by Ann Bryant, is a wonderful discussion-starter on bullying, peer pressure, and dealing with a new step-family. You can guarantee that if I ever do get remarried, my son will be so in love with the guy he'll either be our Best Man or he'll walk me down the aisle himself.
