I didn't like this book at all. This book was a big disappointment to me, because I expected it to be as good as the first books.
In my opinion Anne Rice should never have written this book, because it contains too much religious and philosophical nonsense. In my opinion this book is as bad as Terry Goodkind's Naked Empire.
If you've enjoyed reading the first three books (and even the fourth book), this fifth book may be a big disappointment. You should avoid this book, because it's quite bad.
