Finding out you were wrong about something important can be a letdown. But Poppy is pleased to learn she's not just a Monday. She's a Cusper, a weekday lucky enough to have two powers. Poppy's elation is short-lived when she, Ellie, Logan, and Sam return to Power Academy as camp counselors, only to find themselves out of their element and struggling with the new drama teacher and his disaster of a school musical. When some campers go missing, Poppy and her team of weekdays are on the case. Soon, Poppy begins to realize that much like her powers, the seemingly-perfect town of Nova has some flaws, and the origin of her powers is as questionable as Headmistress Clothes-too-tight Larriby's choice in outfits. If only there were more days in the week!
