Catch-22 is the story of an American bombardier called Yossarian hell-bent for survival during World War II. The non-linear narration is confusing and repetitive. But its unconventional structure contributes to the madness of its characters and their times. Humorous, provocative and unexpectedly empathetic, it is a must-read for those looking for quirky books. Joseph Heller's Yossarian has centuries to live and express the importance of cowardice.
