Find out about some of the coolest gadgets ever. What's the most important gadget ever invented? How do mobile phones work? What about email? What do robots look like? Who said the world only needs five computers? Get the facts. Then read the story 'Bludworld3' and find out what happens when you prefer computer games to real life.

This fantastic book features an exciting combination of both fiction and non-fiction. The non-fiction section enables readers to engage with the subject matter, using dramatic illustrations and bite-sized texts. The beautifully illustrated fiction story appears in two formats - short, simple texts for more able readers and an illustrated 'speech bubble' version of the same story, for those who are really struggling. Part of the Trailblazers series, this book is brilliant for keeping reluctant readers engaged.
