This is the final part of the Saga of Darren Shan, the vampire's assistant. In the previous instalment Darren met again his nemesis, Steve Leonard, and has discovered that Steve's son, Darius, is his nephew. He now has to decide if he will become the Lord of the Shadows and walk the darker side for the rest of his life, or try to change his destiny. The fight between the vampires and the vampanese is still looming, when Darren finds out how his life has been manipulated from before he was born by Mr Des Tiny (destiny). Mr Tiny and his daughter Evanna (a witch who wears only ropes for clothes) play a major role in the outcome of this ending (or is it just the beginning?) of the vampire's assistant.
