In case you missed it, Gaddis's biography of Kennan, mentioned here previously, won the Pulitzer Prize for biography, while the late Manning Marable's book on Malcolm X won the history prize (via); I also happened to read another review of Gaddis, by Frank Costigliola in the New York Review of Books, that I found quite interesting. (He criticizes Gaddis for giving Kennan's later views -- on Vietnam, nuclear weapons, etc. -- too little emphasis.)
Recently published: Rachel Maddow's Drift (on U.S. foreign/military policy) and Timothy Noah's The Great Divergence (on income inequality in the U.S.) are aimed at a broad audience and I imagine will be getting a fair amount of discussion, especially Noah. (Drift is mentioned in this post.)
Lastly, some who are stopping by here may be interested in this (not yet published).
