Nominated Persephone and Hades, Godmother by Ursula Vernon (...you did say it was allowed in the comments), and The Cat Who Became a Queen.

I'm hoping for some combination of Red Riding Hood, Bluebeard, and Robin Hood to be nominated by other people -- I love reading and writing retelling of all of those, but they're also all things it's rather easy to find, so I figured I'd pick obscure options for my last two.
