What a great little book for people who love puzzles and numbers. I found it in the children's library at my local public library, but it was challenging enough for me to have to really think about some of the puzzles. Not only does it contain word puzzles, but it also has quite a few little math tricks to learn. It packs a lot into a small, but thick package. Great for kids, but I also recommend it for anyone who likes to puzzle things out.
