Do remember the first book to make an impact in your life as a child?

I actually DO remember a book that I read when I was a kid, and I read it a few times as I loved it so much. It was called "Follow My Leader" and it was about a boy who lost his eyesight due to playing with a firecracker and he had to learn how to live his life blind. He ended up with a seeing eye dog and it told of how his life changed in the most profound way because of this dog. To this day I have the uttmost love and respect for dogs.
