On the surface, Catch-22 is a fine novel about the U.S Army Air Force in Europe during the 1939-45 war. You do not have to scratch the surface hard to find a classic, timeless novel of the fine line between sanity and total madness. Is Yossarian, the 'hero', totally sane, or utterly, irredeemably insane? You tell me. Catch-22 is unique in its ability to thrust confusion, frustration, despair, insanity, death and plain old fashioned misery in waves - and yet repeatedly surprise you with its sidesplitting humour. When you laugh, you are not laughing at Heller's finely crafted characters, with all their idiosyncrasies, but at yourself, your friends and relatives. Because Heller's situations mirror the daily stupidities that we all put up with, laugh about and cry about. Reading Catch-22 is like sitting through the main feature a second time - you know exactly what will happen next; you know that nothing can change it. You cannot help hoping that it won't be so bad. But, of course, it's worse.
