As long as there are abused children, or even children who believe their siblings have an easier time of it than they, there will be Cinderella stories to heal their wounds.
The Blue Bull
The Brocaded Slipper
Cendrillon, The Cinder Maid
The Glass Slipper
Fair, Brown, and Trembling
Little Burnt Face
The Little Red Fish and the Clog of Gold
The Magic Orange Tree
Vasilisa the Beautiful
. . . and more, of course.
To get through the known variants, you would have to read one a day for a year!
