Previously, I had read Ann Coulter's How to talk to a Liberal and found it entertaining. I love Ann's thoughts on things. The book is mostly a collection of her columns, but they are great columns. This book isn't one of those foundational books that all conservatives should read in order to understand the movement. However, it's a fun read.
I have also read Michelle Malkin's Invasion within the past year. I think she makes a few mistakes, but I agree that the immigration situation must be addressed. I think she does a good job of presenting her case without just listing outrages and trying to provoke an emotional response.
J.C. Watts' What Color is a Conservative was a pretty good book as well. It's mostly biography, and he's had an interesting life. Again, it's not one of those foundational books for the conservative movement. It's also not obviously a campaign biography designed to build support for some future run for office.
Others getting an honorable mention for the past roughly year have been Founding Brothers which received a bit of press when it came out and Lee, a one-volume condensation of Douglass Southall Freeman's four-volume biography of Robert E. Lee.
I'm currently reading Benjamin Franklin's autobiography as well as reading some modern mystery stuff for fun sometimes.

The problem with books like, Let Freedom Ring, How to talk to a Liberal...etc is they are preaching to the choir. Not that there's anything really wrong with that but so often they end up being a litany of what's wrong, why are we in this handbasket and where are we going kind of thing, but short on what to do about it.
