Blood Canticle (2003) is a novel by Anne Rice in which she combines the new characters from her novel Blackwood Farm with those from her previous novels in The Vampire Chronicles and The Lives of the Mayfair Witches trilogy.
The style of this book deviated immensely from Rice's other works, while the storyline also created a very strong (and much-publicised) split in fan opinion. Rice has stated this will be the last of her Vampire Chronicles series.
