Query: DO NOT WASTE YOUR MONEY ON THIS BOOK!!!!!

Sophie's World was horrible!!! The whole book is not even a story, it was just a way for the author, Jostein Gaardner, to get his thoughts out on philosopy to people. I found myself skimming parts of it, and the characters had no depth to them, because the whole book is an annoying trick. Good luck if you buy this- it is in no means a fast read.
