The Hitchhiker Trilogy

The Hitchhiker's Guide to the Galaxy: One Thursday lunchtime the Earth gets unexpectedly demolished to make way for a new hyperspace bypass. For Arthur Dent, who has only just had his house demolished that morning, this seems already to be more than he can cope with. Sadly, however, the weekend has only just begun, and the Galaxy is a very strange and startling place.

The Restaurant at the End of the Universe: The Restaurant at the End of the Universe provides the ultimate gastronomic experience, and for once there is no morning after to worry about.

Life, the Universe and Everything: In consequence of a number of stunning catastrophes, Arthur Dent is surprised to find himself living in a hideously miserable cave on prehistoric Earth. However, just as he thinks that things cannot get possibly worse, they suddenly do. He discovers that the Galaxy is not only mind-boggingly big and bewildering but also that most of the things that happen in it are staggeringly unfair.

So Long, and Thanks for All the Fish: Just when Arthur Dent's sense of reality is at its most clouded, he suddenly finds the girl of his dreams. He finds her in the last place in the Universe in which he would expect to find anything at all, but which 3,976,000,000 people will find oddly familiar. They go in search of God's Final Message to His Creation and, in a dramatic break with tradition, actually find it.

Mostly Harmless: The Hitchhiker's Guide to the Galaxy has, in what we laughingly call the past, a great deal to say on the subject of parallel universes.
