A dash of magic

Rosemary accidentally gave up her family's centuries-old magical baking book to her wicked Aunt Lily. Now Lily is making oodles of money with her television baking show, using recipes from the book. Rosemary is determined to get the book back, and so she challenges her aunt, in front of a live tv audience, to a baking contest, with the winner to have the book.

And the contest is on, Rosemary vs. Aunt Lily, at the international baking contest in Paris.

There are all sorts of fun elements to this story, with magical elderly uncles, and magical talking cats, and a young sister who now speaks like a grownup...and that's not even counting the magical cookbook and the (very real) magic of Paris itself.
