This is my mom's account. I had the pleasure of reading this book in English this year. I can honestly say, it is the single most boring book I've EVER read. You will NEVER find someone my age that enjoys this story. It has no action! No suspense! It isn't deep! Things don't symbolize anything. If they do, then you're thinking too hard. This book is not a classic. It is the worst. I'd recommend copying a dictionary before I'd ask you to read this pile. DO NOT EVEN THINK OF BUYING THIS.

Ex Output:
Negative

If this is the "best of the box" then thank God I didn't buy the box. Most of this stuff should never have left Cobain's closet.
