(Important note: This is NOT a novelization of the comic arc. This is a very different idea. It takes place during season 5 in an alternate universe where the 'Nightmare Rarity' comic arc never happened. Therefor, you don't have to read the comics before you read this story.)
Rarity goes searching for gems at Nightmare Night and finds mysterious crown that makes everything terribly wrong. How will Twilight and her friends use the Rainbow Power against one of the Elements themselves? Who's going to stop Nightmare Rarity before she turns all of Equestria into her great, terrifying design?
(Note: I don't own the cover image.)
(Note 2: Rated T for Teens for violence/action and a little bit of blood.)
