What About the Kids?:Raising your Children Before, During and After Your Divorce  by Judith Wallerstein 
If you have children and were to purchase only one book to help guide you in your parenting through divorce, this should be the book. Wallerstein, one of only several long-term reserachers in the area of divorce, finally wrote a parenting primer after 35 years plus of talking to divorced parents and children. This book is as good as having a best friend who talks to you in an honest manner - sharing important information that you don’t always want to hear but very much need to know and understand. Wallerstein knows her stuff. I think she is valuable, because she is not afraid to talk about the difficulties that children experience. SOmetimes we adults just want everything to be ok, so we forget that children’s vantage points are valid, too, even though they make make us look not-so-nice. She is a useful guide and reminds us that more than anything, our kids need us to be the adults, and this is not always easy during times of extreme stress and change.
