Discord and Celestia have fled from the shackles of the castle and are living free to cause chaos. Only Problem? Celestia doesn't know how. Discord is put through his paces as day after day he must try and make Celestia shake off years of royal etiquette and 'proper' magic training while Celestia worries his magic is having an adverse effect on her free will.
Sequel to Controlled Chaos, Chaotic Control but it's not necessary you read that first. Though it would be nice.
