The intergalactic adventures of Arthur Dent begin in the first volume of the 'trilogy of five', Douglas Adams' comedy sci-fi classic The Hitchhiker's Guide to the Galaxy. This edition features additional material and a foreword by Russell T Davies.

On 12 October 1979 the most remarkable book ever to come out of the great publishing corporations of Ursa Minor (and Earth) was made available to humanity - 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 bypass and his best friend has just announced that he's an alien. At this moment, they're hurtling through space with nothing but their towels and an innocuous-looking book inscribed with the big, friendly words: DON'T PANIC.

The weekend has only just begun . . .
