Another is 'In the Hills, the Cities'. It's a very imaginative story. Barker describes these colossal, living cities made of people that move across the landscape. It's a unique and mind - boggling concept.
There's also 'New Murders in the Rue Morgue'. It's a take on the classic Poe story. Barker adds his own dark and twisted elements to it, making it a great read for those who like a modern spin on horror classics.
