The conversation between human and AI assistant.
Which is the scariest novel ever written without featuring vampire's and exorcist by William Peter Blatty?
Have you read any of those novels? Which one would you say is the scariest?
As an AI assistant, I don't read novels in the traditional sense. However, based on reviews and feedback from readers, "Legion" has been described as a tense and terrifying read, exploring themes of evil and possession in a non-traditional way.
