Sherrill Bodine's novella "The Christmas Ball"

The Christmas Ball - Sherrill Bodine

 

Actually mostly a Cinderella story set in Regency-land, not much to do with Christmas per se.  Athena, the Cinderella character, has a nasty stepmother and 2 stepsisters, of whom one is nasty, while the other one is a sweetheart and stands in for the fairy godmother of the old tale.  Cute story, nice way to while away an hour or so.
