When Rarity is showered with attention over her beauty and glamour, Rainbow Dash begins to feel overshadowed, and her self confidence shatters before her eyes. But maybe a certain spell book can help her get what she wants…

Inspired by the third Narnia film, Voyage of the Dawn Treader. A scene in it urged me to write a Rainbow Dash fanfic. :D
Note: You may find Rainbow Dash a bit out of character in this. Or you might not, it depends on your point of view.
