This is my personal all-time-favorite book by my favorite author, Anne Rice. I find this book to be most intriguing and unique. It's truly a one-of-a-kind well researched and well written book. Where else could one find a fictional story based upon the 'Castrati' in such dark and sensual form?It was because of this book and by the author's own recommendation of a movie based on the life of one famous Castrato known as Farinelli (film: Farinelli 1994), that I find myself immersed into the most fascinating world of the Castrati. I have then feverishly indulged my auditory senses with endless mesmerizing vocals of the Castrati and Opera music which absolutely changed my perspectives in music and art. I would say, this is truly a MUST-READ book.
