"What is TwitterLit? A site that serves up literary teasers twice daily. At 5:00 AM and 5:00PM Eastern Time I post the first line of a book, without the author's name or book title, but with a link to Amazon so readers can see what book the line is from. Why? Because it's fun! The posts are also available for subscription via RSS, Twitter, and email."
