I had no idea what this book was about when I decided to pick it up in the library and read it. The first line struck me like lightning. I had to re-read a couple of times before the meaning sank in. I have never read a book on castrati singers before and, except for Farinelli, have never heard of any other famous castrati and, to tell the truth, never thought much about what the costs of being a castrato singer were. Anne Rice changed all that. The story of Tonio and Guido was so vivid with every emotion that the main characters were feeling that it is hard to remain unaffected after reading this novel. The plot moves speedily but at times it is too convoluted and too convenient. On emotional level, the novel works extremely well.
To addressed some of the criticisms in the previous reviews, I agree that the sexual relationships (be they heterosexual or homosexual) were a tad too explicit but that is the staple of all of Anne Rice's novels so I was not that bothered by them. I wasn't bothered by the characterization of Christine also. I agree that she was bland and uninteresting, or at least not as interesting as she could have been given her unique postion as a female painter during the times where female artists were rare, but I think that her presence in the novel as Tonio's salvation was well realized.
I absolutely loved the description of Tonio's revenge and admired the author for making some hard and heart-breaking choices. This is the most original novel that I have read in a while and definately worth the read.
