For use in schools and libraries only. Join Douglas Adams's hapless hero Arthur Dent as he travels the galaxy with his intrepid pal Ford Prefect, getting into horrible messes and generally wreaking hilarious havoc.

The Hitch Hiker's Guide to the Galaxy has, in what we laughingly call the past, a great deal to say on the subject of parallel universes. Very little of this is, however, at all comprehensible to anyone below the level of Advanced God, and since it is now well-established that all known gods came into existence a good three millionths of a second after the Universe began rather than, as they usually claimed, the previous week, they already have a great deal of explaining to do as it is, and are therefore not available for comment at this time...VOLUME FIVE IN THE TRILOGY OF FIVE

In consequence of a number of stunning catastrophes, Arther Dent is surprised to find himself living in a hideously miserable cave on prehistoric Earth. However, just as he thinks that things cannot possibly get any worse, they suddenly do. He discovers that the galaxy is not only mind-bogglingly big and bewildering, but also that most of the things that happen in it are straggeringly unfair. This is volum three in the trilogy of five.

When all questions of space, time, matter and the nature of being have been resolved, only one question remains - "Where shall we have dinner?" "The Restaurant at the End of the Universe" provides the ultimate gastronomic experience, and for once there is no morning after to worry about. This is volume two in the Trilogy of five.

Sequel to Dirk Gently's Holistic Detective Agency. A passenger check-in desk at London's Heathrow Airport goes up in a ball of flame and Dirk Gently becomes very inquisitive.
