The Medford Public Library welcomes Jarrett J. Krosoczka, the author of the “Lunch Lady” graphic novel series, “Hey Kiddo,” and more. He’ll give a presentation on how he became a graphic novelist, how he writes books, and then answer questions from the audience while he draws. His drawing will be projected onto a screen so everyone will be able to watch up close. Everyone attending is required to register through the library’s online calendar.
