I am a high school junior, and was slightly intimidated to receive such a novel to read over this past summer. And, although I got caught up in the fascinating action involving the murder, I did not understand the significance of this kind of existential novel--well I didn't even know what existentialism is, never mind understand the theories of people like Kierkegaard or Nietzsche.
But now, after fully analyzing this novel over a period of several months, I have come to realize that this book is one of the landmarks in world literature. Not only did it change my life and expand my thinking, but it also gave me insight on the historical perspective of 19th Century Russia. This particular translation (Richard Pevear) was absolutely FANTASTIC, and compares to no other. It is definitely my top recommendation for translations.
This is truly a novel of epic proportions--not exactly bedside table reading. I would say to read at your own risk, but if you do, be sure to relish it as best you can, for once you finish, you will realize that you have read something truly great.
