The Hitchhiker's Guide to the Galaxy by Douglas Adams

An international phenomenon and pop-culture classic, The Hitchhiker's Guide to the Galaxy has been a radio show, TV series, novel, stage play, comic book and film. Following the galactic (mis)adventures of Arthur Dent, Hitchhiker's in its various incarnations has captured the imaginations of curious minds around the world.

The Earth follows shortly afterwards to make way for a new hyperspace express route, 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, in large friendly letters, with the words: DON'T PANIC. The weekend has only just begun.

Continue Arthur Dent's intergalactic adventures in the rest of the trilogy with five parts: The Restaurant at the End of the Universe, Life, the Universe and Everything, So Long, and Thanks for All the Fish, and Mostly Harmless.
