Chris Riddell's fabulously illustrated 42nd Anniversary gift edition of Douglas Adams's classic The Hitchhiker's Guide to the Galaxy. It's an ordinary Thursday lunchtime for Arthur Dent until his house gets demolished. The Earth follows shortly afterwards to make way for a new hyperspace express route, and Arthur's best friend has just announced that he's an alien. At this moment, they're hurtling through space with nothing but their towels and a book inscribed in large, friendly letters: Don't panic. The book is The Hitchhiker's Guide to the Galaxy and the weekend has only just begun.
