For political junkies who like a little modern history with their politics, especially those who may have some familiarity with the work of the late William F. Buckley and/or National Review (I hope I haven't narrowed the field too much) I'd like to recommend a novel titled Getting it Right. It was written by Buckley about four years ago and it tells the story of the three-way struggle between Ayn Rand, the John Birch Society, and the crowd at National Review for the soul of conservatism.
It's a fascinating account beginning in the 1950s and ending with the Goldwater defeat in 1964. Buckley does a masterful job of allowing Rand to skewer herself in its pages, making her look like the megalomaniacal genius that she was. It also provides a fascinating account of how the John Birch Society got started and how it came a cropper. Along the way you meet many of the key players of the time, including Buckley himself. It's a good read, especially for conservatives eager to bone up on the details of this critical gestation period of American conservatism.
