After defeating Power Academy twice, Poppy's ready to kick back and relax! But when Logan finds a mysterious note from his parents, Poppy and her crew spring into action.This time, the search takes Poppy, Logan, Ellie, Sam, and Mark beyond NOVA and into the real world, where everyone is powerless and everything they know it about to be challenged. If Poppy can help Logan find his parents, they'll finally get answers about NOVA, cusp powers, and how it all started. But someone has secretly followed them, and he will go to great lengths to destroy anyone or anything that could expose him. Soon, Poppy will learn she may be more connected to NOVA's origins than anyone could ever imagine, and now, they're running out of time. If only there were more hours in a day.

Twelve-year-old Bertie Blount is great at causing trouble. When she's forced to leave behind her dad and friends in North Carolina so her mom can marry the most boring optometrist in the world, Bertie has a chance at a fresh start. But when Bertie arrives in Pennsylvania, she doesn't just bring trouble; she brings disaster. In a moment of anger, Bertie unwittingly triggers an accident that puts her future stepbrother in a coma. Broken and desperate to make things right, Bertie prays for a miracle. Instead, the universe gives her a pair of supernatural sunglasses, a wise-cracking doppelganger, and a terrifying ghost that sends Bertie on a dangerous mission to find the one thing that just might save her stepbrother's life.

What if your teacher could read your mind just because she was born on a Thursday? Or the kid next to you in class could turn back the clock just because he was a Wednesday? In the quirky town of Nova, all of this is normal. Poppy Mayberry, an almost-11-year-old Monday, should be able to pass notes in class or brush her dog, Pickle, without lifting a finger. Poppy's Monday telekinesis ability has some kinks and that plate of spaghetti she's passing may just end up on someone's head. If that's not hard enough, practically-perfect Ellie Preston is out to get her and Principal Wible wants to send Poppy to remedial summer school to work on her powers! It's enough to make a girl want to disappear. If only she were a Friday.

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!
