Kids who are enthusiastic about codes may want to try decoding the messages that are referred to in the text and can be found (along with worksheets) within the distinctive illustrations. While Nana's work at Bletchley may not be meaningful to children too young to understand the context, codes and secret messages have an enduring appeal for many children. - Carolyn Phelan; Booklist ReviewsCharlotte loves puzzles.
