Query: THIS BOOK IS COOL!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Let me just say that this book rules!! The background story of one of the most amazing character in literature is finally told! From his beginning years to the last six months of his life, Erik's story is told in breathtaking detail, from his POV to those around him including his mother, an Italian stonemason, his friend the Persian of Leroux's story, Christine, and Raoul.I definetly recommend this book! Leroux himself would be proud of this story!
