Jennifer Weiner

The book is "Goodnight Nobody"
She is a wife with 3 kids who sets out to find out who murdered a woman in her neighborhood that she barely knew, just because she needs something intelligent to do and she used to be a reporter for a tabloid who reported on celebrities and their latest rehab visits and affairs, but a journalist anyway! She lives in Connecticut in the wealthy neighborhood, she feels stupid talking about whether the milk at the store is really organic or not and feeds the children McDonald's food which would cause a scandal so she hides the evidence and wipes off the ketchup before going somewhere. She married someone she didn't love, but merely liked and when an almost lover from her youth appears she starts to wonder if she didn't make a mistake and if she did, how can she fix it now with 3 small children? She has not made a single friend in the Martha Stewart clone crowd and nor is she happy paying 2 thousand a month for the exclusive nursery school her kids go to because all they do is watch the kids finger paint.
Yes, she mocks the rich even as she is one of them. She feels out of place. Then she finds out her best friend who is an intelligent Paris Hilton had her almost lover almost deported out of the country.
So who killed this woman who had ghostwritten a column called "The Perfect Mother" who really did seem to be a perfect mother who is found laying on her kitchen floor with a knife in her back?
This is the same author who wrote "In Her Shoes" and if you didn't read the book then you probably saw the movie.
I have not finished this book yet, because I am so enjoying the journey of reading it.
As for what the title is about, all of you with children know the famous book "Good Nite Moon" for wee ones in which the author says goodnite socks, goodnite clock, goodnite nobody and in the book the child Sophie asks "Who is Nobody" and she says she doesn't know but she thinks that Nobody is her. Her husband is seldom there and she has no friends and her children seem to be always wailing or crying or spilling something on her constantly, as any mother knows. This book talks of motherhood as it really is, though she loves them. She is so easy to identify with and writes so clearly one could laugh out loud with her and feel like she is a friend.
She certainly seems like she would be a great friend and she has written a very good book.
