This was a strange book. It was also a lot more compelling than I expected it to be. And I never expected a happy ending. Maybe I read it wrong. It seemed to me that the main character, Raskolnikov, repented at the end of the book because he realized that his girl, Sonya, managed to maintain her decency in spite of being a prostitute (she was forced into this by her father) because of her reliance on God. In a warped sort of way, I found that to be a positive ending.
