Well, 'The Book of Blood' is also highly regarded. It sets the tone for Barker's exploration of the macabre. The way he weaves the story, with the central idea of the book that is written in blood, is both disturbing and captivating. It shows his talent for creating stories that are not just about scaring the reader but also making them think about the deeper themes within.
Another great one is 'In the Hills, the Cities'. This story is quite complex and thought - provoking. It uses Barker's unique imagination to explore some really strange and fascinating concepts. The vivid descriptions make it a standout among his works. It makes you question what is possible in the realm of horror and the surreal.
