"Goddess of the Market: Ayn Rand and the American Right," by Jennifer Burns

Gonna read "Ayn Rand Explained" first, since it's shorter. "Goddess of the Market" looks like it might be the better of the two books, though, judging by their descriptions. Oh well, I'll get to it eventually.

I also still have to finish reading "Ayn Rand Nation," by Gary Weiss... >.>
