School, it seems, is back in session.
Jeff Gilbert knew little about the Harry Potter series of books by J.K. Rowling, only what he had heard here and there at home. In 2010, he took up his daughters' challenge to spend his first free summer as a professor reading and commenting on the series. Well, he got pretty far that summer but the rest of life slowed him down. He's still working on it and looks forward to the day he finishes.
