The Time and Space of Uncle Albert

This is the best introductory exposition of relativity theory ever written. As a book, it occupies that strange middle ground between fiction and non-fiction, much like the Magic Schoolbus books (where should the librarian put them?), but it is for a somewhat older age group. By somewhat older, I mean only that it has fewer pictures: I'd put it in with all the Milton Bradley/Parker Brothers games, and say it's for ages 8 to 80. For ANYONE who is interested in relativity, no matter what their age, this book is a perfect place to start. Check your library, and if you can't find it try to place an "out of print" order. This book is a gem.
