This site offers links to authors who are willing to Skype to classes that are reading their books in school or for book clubs. Although designed for middle school students, there are also links to authors of adult books.
According to the site host, "I started it because I’ve found that virtual author visits are a great way to connect authors and readers, and I realize that many schools facing budget troubles don’t have the option of paid author visits. With that in mind, this is a list of authors who offer free 20-minute Q and A sessions with classes and book clubs that have finished reading one of their books."
