Story: The Puzzle of Puzzle

[Normal] How puzzling! Anyway I'm going to start leaking non-friendoff stories into the site now.  Here is one from a new author, Polecat.

Description: An unknown pony is found unconscious in the middle of a storm in Ponyville, devoid of a past and a cutie-mark. With help of several of the ponies there, she gains friends, gains a job, and eventually unravels the mystery.
