As a parent with a young daughter, I was seeking a book about children and imaginary friends that contained the following: humorous/interesting/informative stories about children and their imaginary friends; how to react/behave/deal with the children and their make-believe pals; proof that my child isn't wacky - that they are quite normal despite possessing a very active imagination; and the exciting promise of what kind of adult my child might become (from influence of having imaginary friends.)
This book was woefully inadequate for my needs. Although I was reassured that it's very normal for children to have imaginary friends, none of my other expectations were met.
The main problem I had with this book is that it reads like a graduate thesis. The author details results of many surveys and research projects in a dry, professional manner with little or no warmth and humor. I think my first clue to the style of this book would have been the back jacket where all praises were written ONLY by professionals in the psychology field.
Unless you are psychology professional, I doubt this book will suit your needs.
