Banned Books Week 2020

Our theme for 2020 is Lifelines: books that help us get through periods of isolation. "Books" can be any one-way form of communication: a box of letters, a podcast, skywriting -- anything the recipient can't easily reply to. "Isolation" can be either physical or social: an astronaut alone in a spaceship; a person in a place where no one speaks their language; someone in prison. The stories don't necessarily need to have a happy ending, but they do need to end on a hopeful note. And of course they should follow all of the standard Cast of Wonders guidelines.
