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.
