In fiction I have been reading the novels of John Ringo. Most are military sci-fi. I have read most of the Posleen War series, the Council War series, the Troy Rising series and also The Last Centurion. Tomorrow I will probably start Elmer Kelton's The Time it Never Rained.
In nonfiction I always have several books going. I just finished a monograph by Richard Epstein, Why Progressive Institutions are Unsustainable. I am about half way through Law Legislation and Liberty, Volume 2 by Friedrich A. Hayek. I am also reading a book about the Atkins diet. (BTW my wife and I started the diet a bit more than 2 weeks ago and have both lost some weight.) I am also reading The Guns of August by Barbara W. Tuckman.
Next up will be some ecomonics, I have not decided but it is between The Theory of the Leisure Class by Thorstein Veblen and Man, Economy, and State by Murray N. Rothbard.
I have about 3 dozen books in the queue after that.
