Nice reading Bruce!
I don't know the specific book, but Enid Blytons "The Famous Five" books were something I loved, growing up. The four kids and their dog going on all kinds of adventures, helping a young mind escaping the limitations of the physical world and go to various places of the imagination. Had the very same "red" D&D basic rule book too
