She would survive the zombie run.

For some inexplicable reason,  she was invisible to them.

Sure that they were dwindling in numbers she watched mystified as a group entered the graveyard and started to dig up the lately interred.  The clank of shovels and intensity of the zombie's cause made her shiver.

Daring to venture close for a better look,  her gag reflex reacted to the stench and she retreated.  Confused by this eerie behavior,  her thoughts wandered to her memory.

Her parents died horribly.  they had hidden,  all of them in a cave at the edge of town.

On the day the zombies discovered the hide,  she had been foraging for food.  She returned,  in time to hear her mother's screams and father moan.  At the mouth of the cave she witnessed her mother stripped and torn asunder.  Unable to stop herself she cried out.  The whole pack turned and came toward her.  she ran until she could run no more and resigning herself to fate lay down under a bush.  They came to within inches of her and passed on by.  It was then she realized her power.
