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.
One month after their parents' disappearance, the third-grade Huit octuplets deal with a malfunctioning refrigerator and try to win the love of the only boy in their class at Valentine's Day, while Dorinda discovers her special power and gift.
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.
The Huit octuplets discover Marcia's special power--the ability to see through things--which helps when their evil neighbor calls Social Services to report that they are living alone because their parents have not returned from wherever they disappeared to.
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.
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.
The Huit octuplets, each of whom has now discovered her power and received her gift, finally learn where their parents are, but before they can attempt a rescue they must face the Other Eights and a very scary aunt.
