Read the book and found it hard to put down. If Gaston Leroux seemed to some not to have been a good writer, I didn't notice that he wasn't. I was able to relate the book to the 2004 movie as it followed Leroux's story pretty well. While the movie concentrated on the romance aspect of the story, the book itself was more involved in what seemed a few plots, e.g. murder, mystery, romance, horror and I even found some humour. Good book, even with it's sad ending.
