Henry Winkler is absolutely brilliant! I bought book 1 for my 9 year old son a while back and he told me he wanted more Hank Zipzer books. I was thrilled because he is not a big reader like I am. He is more into outdoors and sports. He was diagnosed with ADHD last year and even though the books don't talk about ADHD, it is easy for my son to identify with the struggle that Hank has and they make us laugh out loud!
