My libertarian science-fiction novel, Withur We, now has a trailer you can see on Youtube and other similar sites. http://www.youtube.com/watch?v=Fk9WmkIW5Ew
Also, for those interested, you can get it on Kindle for only $5.99. http://www.amazon.com/With%C3%BBr-We-ebook/dp/B003R0LPEA/ref=sr_1_2?s=gateway&ie=UTF8&qid=1285383540&sr=8-2
If you’re looking for some Rothbardianism in your sci-fi, give it a try! As always, the free PDF and the hard copy version are available from the website. www.withurwe.com
