I recently read the gentlest, most thoughtful post-apocalyptic novel I've ever read. It's about how our lives would change if we simply... ran out of oil. No zombies and no comets. No earthquakes and no viruses... just not enough oil to make our country go. It's called World Made By Hand and it's truly flashlight worthy.

I selected the following (flashlight worthy) novels for their focus on what comes after the end, rather than the end itself. They attempt to answer the all-important question: Now what?
