Query: Quick and excellent read

This has to be one of the best books I have read in a really long time. It gives a brillant depth to the phantom's life. Though I felt that the portrayal of Christine's character made her too "weak" (I always thought she should be strong), the rest of the book more than makes up for this one small shortcoming. I called out of work to finish reading this book! I recommend it to any fan of Phantom of the Opera. I can't stop talking about it.
