[[The Pluto Files: The Rise and Fall of America's Favourite Planet by Neil deGrasse Tyson]] is aimed at adults, but is written in such a clear, simple and engaging way that younger space geeks won't find it pitched too high over their heads. [[Dinosaurs (Henry's House) by Philip Ardagh and Mike Gordon]] also blends a comic style with non-fiction (and a book on space will follow in March 2010). [[George's Cosmic Treasure Hunt by Lucy Hawking and Stephen Hawking]] is well-worth a look for confident readers who love everything about space.
