Comets 

Millions of years ago a giant meteorite killed all the dinosaurs. Find out how. Will humans all be killed in the same way? Find out what we can do. Is there life on the planet Mars? Scientists think maybe the answer is yes. Find out why. Get the facts. Then read a scary fiction story about what might happen: 'Doom from Space’. 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.
