I'm going to be honest here and say that I really don't remember many details about this book other than one very important one.
I very distinctly remember this being the very first Chapter book I ever read from the school library when I was 11 or 12. Up until then, all the books I had checked out from the library had been non-fiction. We were forced to check out a chapter book and do a book report, so me being a young boy this looked cool so I took it.
As I said, I really don't remember much about the book itself, but what the book did to me I remember very well. Reading this book from cover to cover, and actually liking the "ordeal" was the beginning of my lifelong love of reading.
I have read thousands of books since that time about 45 years ago, but this one has a very special place in my heart, because this is the book that started it all for me.
