I have a camera and I know how to use it.
I have done a bit of Skyping with classrooms of various ages, and I'm completely addicted. So, for the time being, Skype visits with young readers are free to any school or library, especially if the kids involved have read one of my books. The visit can't be more than a half-hour long and usually will consist of an informal chat or a reading followed by Q&A.
Email me at firstname.lastname@example.org, and let's see what we can set up.
