Query: a harsh yet rewarding book.

This book at times can be difficult. Both because of what the narrator says, and because of the author's writing style. Mr. Slocum (the protagonist of this book) is amazingly similar to the main charactor of Albert Camus' book "the Stranger." They are both estranged from society, and see it in an emotionless light. Many of Slocum's thoughts and decisions, although cold and often unheroistic, are on some level understandable. Liking "catch-22" doesn't necessarily mean you'll like "something happened." the writing style is very different. Also the humor is very different. Instead of "catch-22's" absurdist irony, most of "something's" humor is very dark and sadistic. This book's greatest affect on you is after you've put it down. The more you think about it afterwards, the more you get it. Although more difficult to read than his earlier work it's infitely more rewarding.
