I read Imajica by Clive barker and I was not impressed. I liked the parts of the story that took place in the "real world" but not the parts that took place in the "Imajica world" which is pretty much the second half of the book.
The most merciful thing in the world, I think, is the inability of the human mind to correlate all its contents. ... The piecing together of dissociated knowledge will open up such terrifying vistas of reality, and of our frightful position therein, that we shall either go mad from the revelation or flee from the light into the peace and safety of a new dark age.
~ Howard Phillips Lovecraft
