Hitchhiker's Guide to the Galaxy

Arthur Dent thought his day was going badly when someone tried to demolish his house.

Then someone demolished his planet.

Rescued by his friend Ford – who is not a human from Guilford, but an alien from somewhere in the vicinity of Betelgeuse – Arthur is flung into an adventure among the stars. He will face aliens, robots, world-builders, and that girl he quite fancied who turned him down at a party one time. All in the name of research for the greatest book in the galaxy.

He just has to remember not to panic.
