Things to like about this story: A cute take on the Cinderella story; the Doctor actually factors into the story, which is not the case in most of the Time Lord Fairy Tales; the not-so-much-glass slippers are a nice tweak to the tale.

Things not to like: There's no explanation as to how or why the Doctor picked this particular person for his mission; he doesn't warn her about the danger he is sending her in to face, or the consequences of not following his instructions.

I can see reading this to a kid who likes Doctor Who and already knows the Cinderella story.

I really don't have all that much to say about this one, where The Garden of Statues was an original fairy tale, and Frozen Beauty was taking inspiration from the fairy tale to basically tell a new story, this is effectively a retelling of the fairy tale with a Doctor Who coat of paint.

It does strike me as weird that one of the Time Lord's fairy tales involves The Doctor as a heroic figure (the Eleventh Doctor at that), but here I can overlook that a bit more. Also the perfect choice for a Doctor to tell a fairy tale about, given a lot of his stories very much feel like them.
