Thirteen-year-old Pandy is hauled before Zeus and given six months to gather all of the evils that were released when the box she brought to school as her annual project was accidently opened.
On their way to find the third evil, laziness, Pandy and her friends, Alcie, Iole, and Homer, face many dangers after Pandy falls from Apollo's chariot and her friends are captured by pirates who intend to sell them into slavery.
As Pandy, Iole, and Homer travel to Baghdad to seek another deadly evil--rage--they face a lethal sandstorm and worse, while Alcie is aided by Persephone, the queen of the underworld.
