Eleven-year-old Miranium's summer is going down hill fast: her best friend, Thomas, has moved away; her know-it-all nemesis, Tamika, has moved too near for comfort; her parents are stressed since her father has lost his job; she has just blown up the microwave with an ill advised experiment (destroying her own cellphone in the process); and, worst of all, her beloved cat, Sir Fig Newton, has developed diabetes. There is no money for his medical care, and her parents want to re-home him--but Mira is determined to raise the money somehow even if it means turning to Tamika for help.
