Sophie's World - A Novel About the History of Philosophy (30th Anniversary Edition) | Jostein Gaarder

One day Sophie comes home from school to find two questions in her mail: "Who are you?" and "Where does the world come from?"

To unravel this riddle, Sophie must make use of the philosophy she is learning. But the truth is far more complicated than she could have imagined...
