Autumn Breeze has amnesia. How she got it? No body knows. And she doesn't remember. All any pony knows is that she was found on the docks with blood pouring out of her head, with a fading cutie mark and a fading heart beat.
Feeling like a random stranger, Autumn writes a letter to a random pony, signing off as 'Sincerely, Random'. Little does she know that the results of this letter are about to change her life
Not that her loss of memory hasn't already.
