The Law by Frederic Bastiat (awesome, short, soooo many quotable quotes)

Healing Our World by Dr. Mary Ruwart (old version available free)

Haven't read any of his books (have listened to many lectures and radio show), but something by Harry Browne should do quite nicely. I've heard great things about Why Government Doesn't Work

Myths, Lies, and Downright Stupidity - John Stossel (do check out his excellent Fox Business show "Stossel" on hulu.com, and look for his old 20/20 specials on libertarianism - they're fantastic)

good economists: Peter Schiff, Walter Williams, Thomas Sowell, Walter Block

You might be better off waiting til you get more comfortable with libertarianism, but G. Edward Griffin's Creature From Jekyll Island is a must read. It's more about the monetary system and the Federal Reserve than libertarianism in general though.

I haven't read anything that makes a good argument against libertarianism, but can recommend a guy who makes a seemingly good argument against capitalism and for socialism - Michael Parenti. I haven't read any of his pro-socialist books (but have one on foreign policy called The Terrorist Trap which is quite good and very short. Libertarians and socialists tend to agree on not inviting war and not waging war). But I have listened to his pro-socialist lectures - they're well delivered and impassioned and a person who didn't know any better would easily be tempted. They're worth listening to to use his arguments and twist them to actually make the case FOR libertarianism. He'll use some faulty facts/data that leftists typically do such as "Hoover was an ardent free-market advocate and we can blame him and capitalism for causing the Great Depression" (we can blame him for the depression all right (prolonging it, to be specific), not b/c he was a capitalist but b/c he really started all the policies that FDR continued when he got into office)

It's not a defense of conservatism, but Liberals should read Healing our world in an age of aggression by Mary Ruwart.

This book changed my life, and view of politics. I was raised by card carrying members of the US Socialist Party.

As a former socialist, I recommend "Healing our World: In a Age of Aggression" by Dr. Mary Ruwart.

Don't try to "subvert her without her knowing", be forthright with your intentions.

If she likes to read or is willing to read, possibly suggest a "book swap" or just recommend her a book about libertarianism. For someone who might be coming from a more liberal or progressive persuasion, I would recommend Healing Our World by Mary Ruwart.

These two books started a philosophical shift in my life.

Also, Healing Our World by Dr. Mary J. Ruwart. It made my realize how wrong I was in my previous
