The Door by the Staircase by Katherine Marsh

Mary's life is like a fairy tale. Unfortunately, it's the first part of the tale. She's been orphaned and left to one of the less desirable places to live. There's no hope that she's going to be adopted so she tries to escape instead. She's thwarted by a strange wind which turns out to be a good thing since a strange woman, Madame Z, shows up the next day and wants to adopt Mary. From then on, Mary learns the ins and outs of living with Madame Z and in the strange new town of Iris which seems to be full of tricksters and magicians. But are some of them using real magic? That's not possible. Is it?
I very much enjoyed this story, especially the way some of the usual fairy tale tropes are subverted to make a truly charming tale.
