Mostly Harmless by Douglas Adams

Mostly Harmless is a novel by Douglas Adams and the fifth book in the Hitchhiker's Guide to the Galaxy series. It is described on the cover of the first editions as "The fifth book in the increasingly inaccurately named Hitchhikers Trilogy".

The fifth hilarious novel in the classic "Hitchhiker's Guide to the Galaxy" series follows the exploits of Arthur Dent, who has to adjust to a new life when his spaceship crashes on a remote planet. "If you were hoping for more of the zany, nonsensical, mayhem produced in the earlier books, you're in luck." --"The New York Times Book Review."
