I first read Atlas Shrugged in 2007, then followed quickly with The Fountainhead, Anthem, and We the Living. From 2008 onward, I have focused on the non-fiction works of Rand and Peikoff.
Some related books I have enjoyed are:
History of Western Philosophy (W.T. Jones), The Last Days of Socrates (trans Hugh Tredennick), Great Dialogues of Plato (trans W.H.D. Rouse), The Art of Reasoning (David Kelley), Nizkor Project: Fallacies -- http://www.nizkor.org/features/fallacies/
