What pair of authors used themes and characters from a fairy tale published in 1812?
Snow White "Snow White" is a 19th-century German fairy tale which is today known widely across the Western world. The Brothers Grimm published it in 1812 in the first edition of their collection "Grimms' Fairy Tales". It was titled in German: Sneewittchen (in modern orthography "Schneewittchen") and numbered as Tale 53. The name "Sneewittchen" was Low German and in the first version it was translated with "Schneeweißchen". The Grimms completed their final revision of the story in 1854.
The Fairy's Mistake "The Fairy's Mistake" is the first story in a two volume set of six stories called "The Princess Tales" by Gail Carson Levine. Published in 1999, two years after her Newbery Honor winning novel "Ella Enchanted", "The Fairy's Mistake" follows along the same lines by taking the well-known fairytale Diamonds and Toads and turning it on its head. The story focuses on identical twin sisters Rosella and Myrtle, whose respective rewards and punishments end up doing exactly the opposite of what was intended.
