I just love reading books like this, absolutely stuffed full of number puzzles, patterns, palindromes and anagrams. It's the story of a boy, Elliot, who is being bullied at school because he suffers from autism. His only refuge is in the school library, where he spends his breaktimes and lunchtimes helping as an assistant. Whilst working in there one day, a serious crime takes place in the school office. Eliot comes up with an extremely clever (although also extremely illegal!) plan to get revenge on his tormentors. The clues to the mystery are all hidden inside the pages of the book, although you'll have to work very hard to find them.
A very entertaining and quirky book that requires a bit more thought than most. I thoroughly enjoyed it and am sure that it will definitely appeal to its target audience, boys between nine and twelve. It is one of the books in the Cold Fusion series, published by Ransom, in which 'the reader will be stretched with stimulating ideas'. I'm going to keep an eye out for other books in the series to add to our school library, as I have a feeling that they could be very popular.
PS- There's even a clue to the mystery hidden on the front cover!
