You've managed to get your hooves on a first-edition copy of the new textbook for Twilight Sparkle's school of friendship in Ponyville! Why not crack it open, enjoy the "new book smell" and see what's inside?

Following her humiliation at the hooves of Twilight Sparkle, Trixie is left broken and alone. All alone in the world without a friend to care for her, she descends into a state of depression and remorse.
