Here is the fifteenth magical installment of the New York Times and USA Today bestselling series of fractured fairy tales for fearless kids, now in paperback!

Put on your dancing shoes!

Believe it or not, there's a fairy named Maryrose LIVING in my house. And she's sending me and my brother, Jonah, through the magic mirror and into the story of The Twelve Dancing Princesses. There, we meet the twelve sisters who sneak out every night to go dancing. But Jonah and I have our own mission. It's up to us to find the enchanted object that will give Maryrose her fairy powers back.

So now we need to:

-Get our hands on an invisibility cloak

-Follow the twelve princesses to their secret hideout.

-Learn some VERY complicated dance steps.

-And avoid being thrown in the dungeon.

We better wiggle our way out of this magical mess or we'll never help our fairy friend in time!
