The wildly successful local author – you might remember the Spielberg-helmed adaptation of his Ready Player One – unveils his young-adult novel about a girl who helps a group of bats find a new home in Austin when their country home is destroyed. Appropriately, this booksigning takes place under the titular bat bridge near the old Austin American-Statesman building. Nerd-famous (and we mean that as a compliment) Felicia Day leads a discussion with the author before the signing line gets going. – James Renovitch
