I just finished "Freakonomics" liked it. I also just finished "Amazing Maurice and his educated rodents" by Pratchett, loved it... I am currently reading "The life of John Muir" - very intereting (not right this minute of course!) I am also reading
http://www.amazon.com/gp/product/037...lance&n=283155 "First Great Triumph: How Five Americans Made Their Country a World Power" which is sortof good, but looooong.... It is bascially a history of our imperialism....
