Naked Lunch - William S. Burroughs
Burroughs, he's a kook. He didn't even need drugs to be one - he just was. This is his non-linear series of vignettes, cross crossing the globe while under the influence of various substances≥ A staple of beat literature and considered a 'Top 100', still. *small paperback, rare-ish, and in great shape for its age.
