This is a very interesting and enthralling book of really rather complex puzzles! I liked the thematic approach to the sections and puzzles in the book with the over reaching ideas nicely joining the activities together. The challenge for many of the activities was very cleverly interwoven with simpler, more random or just plain fun information, facts or tests. As well as the really varied and enterprising variety of puzzling tasks.
