I have long ago noticed the struggle and love and hate relationship Anne Rice has with her God and the religion. In one of her best books (IMO) Memnoch the Devil, she has devoted almost all the book to God/Devil interaction.
While I enjoyed her books, most notably “Interview With the Vampire” , “The Vampire Lestat”, “Merrick” and “Blackwood Farm”; I found other books to loose my attention, due to the repetitiveness, the regurgitation of the story line of her previous books.
I enjoyed her Mayfair Witches too and found it most enjoyable when she had her Vampires and Witches meet. However, she started loosing the edge.
Her writing style is beyond reproach, so there is no doubt that the new book, what ever subject she might choose, will be worth reading. I hope that the new (rediscovered) interest in her religion gives her writing the passion and spark she lost.
