Required to attend summer school after moving to Chicagoland, thirteen-year-old manga-lover Megan Yamamura needs help from twelve-year-old computer genius Raf to escape the maniacal principal's mind-control experiment.

As the founders of the Chicagoland Detective Agency, a haiku-writing girl and a boy with a talking dog have more than enough cases on their hands (and paws) when a friend vanishes, a mummy's amulet disappears, and an evil scientist stalks human brains and hearts.

Raf, Megan, and talking-dog pal Bradley are abducted by aliens from the planet Fnarf III, where dogs are in charge and people are pets, to help locate the missing Princess Zu-La.
