Luck and the Principle of Relativity.

"Luck and the Principle of Relativity'' is the first piece in a series of short stories which describe the experiences of a nameless girl in a post-apocalyptic America. This story is intended primarily as a thought experiment: although confronted with fantastic circumstances, the narrator is not focused on the existence of the ''Sleepwalkers,'' i.e. the zombies that people the background of her world, but rather on her own physical and emotional survival in a time of chaos, where the real danger is found in the economic and psychological climate of the new reality.
