Ex Input:
Cities Of The Red Night is one of the most enjoyable books I have read. The novel has different storys that as the novel progresses intertwine. The books presents situations that are unbelievable but because of Burroughs genius you are convinced of that they are happening in a world not too far from are own. I think he was trying to show the questionableness of what is presented to us as reality. This book also has some of the most vivid pictures and unforgetable lines that I have read. It is Burroughs masterpiece.
