Oh, no. Oh, no. Oh, no. Oh, no! May is almost over and that means only one thing: Petal's month is about to begin. For most people, this would be a good thing. They would look forward to discovering their gift and their power. But not our dear Petal. As far as Petal is concerned, it could stay May forever.

At least the sisters have some excitement in their future: The wedding of Aunt Martha and Uncle George will bring them, the Petes, and the cats to Paris, where fun--and a little bit of danger--will come as surely as the changing of the month.
