Any novels by the master of speculative science fiction and techno-fiction, Neal Stephenson. With books as thick as textbooks and nearly as dense, Stephenson has a way with big ideas that span space and time and reality. He is by far one of my favourite authors—and, trivia for you—if you were to ask me which book tops my list of all books by all authors, I would undoubtedly tell you that I have read Anathem at least twenty time, so beat that!
