Changes

This book, like the previous two, isn't merely a quick dash from danger to danger, however: it demands more of its readers and will appeal to people who enjoy sitting down with a pen and paper to work out the clues rather than be spoon-fed the answers. Ruby is a gifted code-breaker, and she and her best friend Clancy often communicate by means of elaborate codes which readers are allowed to try for themselves before the answers are provided. There are helpful extracts from the Spectrum spy handbooks to study, and a whole section on how to use chemistry to communicate with other people. And the hardback edition even includes a scratch and sniff advert, the importance of which will be revealed as the story progresses. This is a fun read which skilfully combines action and information, and it will definitely appeal to readers who love using their brains and thinking things out for themselves. Who knows: maybe the young people who enjoy reading these books today are the secret agents of tomorrow?
