Barker's literary works are definitely more macabre than some of his contemporary authors and he has never been one to shy away from sexuality in any way. He is most famous for his creation of the Hellraiser character Pinhead and the countless movies associated with them. Barker himself was only associated with the first few and the rest have been bad ripoffs.
Barker has written many books including a few young adult and has become one of the best horror writers of our generation. All have been critically acclaimed in horror circles and he continues to offer up his own unique view of the world. When he isn't writing, he paints macabre paintings that reflect his own twisted dark thoughts.
He has also penned comic books, excuse me, graphic novels and even a video game for Playstation 3. There doesn't seem to be anything that Barker hasn't tried out at one point and time. After several years of writing young adult fiction, he has once again entered the foray adult fiction. I for one am looking forward to many more years of his works.
I don't think there is a modern writer that can match the pure imagination and depth of horror that Barker can conjure. That's why I was disappointed when he started writing young adult fiction because you can't go all out on the teen audience.
