The end of May makes Petal, the sixth sister, nervous for the month of June--her month--to begin, but the Huit octuplets have a wedding to look forward to, the Petes, and the cats in Paris.
During the month of June, Petal, one of the eight Huit octuplets, gets her power, which she uses to great advantage when Crazy Aunt Serena tries to kidnap Rebecca and throw her off the Eiffel Tower while the rest of the family attends a wedding.
Petal is nervous about the coming of the month of June. That is when she will receive the power and gift that will help the sisters find their missing parents. In the meantime a wedding will bring all the Petes and the cats to Paris for some fun and a little bit of danger.
