Playlist for the Apocalypse

It's been eight months since Betty and her traveling companion has seen a living human. It's been nine months since the world, in short, has ended. Betty is only now realizing that the world is screwed and it's not going to magically right itself, so the only way on is forward. Somehow, she- and Sweet Pea- are going to survive this. Sweet Pea/Betty, Zombie Apocalypse!AU
