The state’s biggest literary event is one of the most family-friendly Downtown events of the year, known as much for its storybook readings and illustration demonstrations for kids as it is for its panel discussions and author appearances for adults. Balancing things out is what’s sure to be a boisterous chat with headliner John Waters — yes, the director of shock-and-raw films such as Pink Flamingos, but also the writer of a fat handful of books, including the novel Liarmouth and the auteur’s exercise in cross-country hitchhiking, Carsick. Bilingual options will include a panel discussion headed by writing group Autoras de Vanguardia and an Aztec calendar coloring workshop (also in Nahuatl).
