Twilight's been spending her days alone in her library. Rarity rather misses the bookworm. A little magic meddling is all she needs for love.

The usual blame to fourths, Cake Eater, and the source of all Raritwi. Special blame to FanOfMostEverything for "Also, story where Rarity gets turned into a book to Twilight's delight when?" comment, so this happened.
