On New Year's Eve, the octuplets Huit--Annie, Durinda, Georgia, Jackie, Marcia, Petal, Rebecca, and Zinnia--discover that their parents are missing, and then uncover a mysterious note instructing them that each must find her power and her gift if they want to know what happened to their parents.

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.

As the Huit octuplets prepare for a St. Patrick's Day parade, Georgia discovers her powers and uncovers the substitute teacher's secret.

With the arrival of August, Zinnia, the youngest of the Huit octuplets, eagerly anticipates getting her power and gift, both of which hold big surprises that are revealed to the sisters on their eighth birthday.

April Fools' Day is long and hard for the third-grade Huit octuplets, but it is nothing compared to the challenges of Tax Day, through which Jackie discovers her special power and gift and learns more about their parents' mysterious disappearance.
