Currently raising three teenage boys, 15 year-old twins and a 14 year old, I purchased the book for issues we’re having with one of the boys. However, within the first few lines, I realized that it is applicable to all of them! Their father read it, too, and said exactly the same thing. Its helped us understand the changes and challenges they are going through, as well as give us tools to use in parenting them. Very good book, would recommend to anyone raising or working with boys.
