"Doors of Perception" is by Aldous Huxley, one of my favs, he was really into drugs and married a girl that lived a block away from me
I'm now reading "The Shining". I always wanted to see the movie but I got the eBook first. After that I'm going to begin in Poe's "The Narrative of Arthur Gordon Pym of Nantucket", sounds wicked too...
Anyway, hahaitsdoogle, if you want free ebooks, check project gutenberg.
