[1] 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.
[2] 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.
[3] The widow Pickering sends her daughter Rosella to the well to fetch water where she meets an old woman who is actually the fairy Ethelinda in disguise.
In the original tale, the wicked mother drives out the younger daughter who has jewels fall from her mouth and a prince finds the girl wandering the woods.
[9] Gail Carson Levine keeps the beginning of the tale, but plays with the idea that all rewards and punishments do not go exactly as planned.
