I finished listening to Sarah Vowell's The Wordy Shipmates on Friday, and just want to say, I highly recommend it. Even if you have no interest in 17th Century Puritan America, Sarah Vowell tells a great story and makes it relevant for today. And funny to boot. I would really recommend the audio book as well, there's nothing like listening to the author telling the story herself.
And for your enjoyment, here's a little clip of Sarah Vowell on the Daily Show. I was still laughing ten minutes later.
On a side note, when I searched Amazon.com for Sarah Vowell to find a link for the book, the first thing that came up was a book about Sarah Palin. I'm sure Sarah Vowell would love that.
