Trixie finds herself in a fix after the first events in Ponyville and she can't seem to make it anymore. She's so desperate that when a complete stranger offers her a job that takes her to a frozen wasteland she snatches it up without a second thought.

Little does she know that she was chosen instead of picked up by chance. Because Night Light, Twilight's father, seems to let more than he's letting on. And why is he calling himself Crescent?
