Green Apple Books on the Park in San Francisco, Calif., shared a seasonal chalkboard on Instagram: "Reading Stories in September... is an Autumn to Remember.""We're still holding out that it's summer until the equinox hits properly, so this sentiment holds true! That said, it’s not too early to get your cozy fall reading on. Let us help you squirrel some books away. Shoutout to Green Appler Peyton for keeping our chalkboard cute."
