Scott, an 11-year-old boy, moves to Goodborough, New Jersey, because his mother has to move there for her job at Goodco Cereal Company.
Scott befriends twins, Erno and Emily Utz, and a tiny leprechaun named Mick.
Mick is friends with Harvey, a talking rabbit. The two escaped from the evil Goodco, which had been holding them captive. Goodco wants them for their magical powers and to use them in commercials. Mick and Harvey are being pursued by some very dangerous people from Goodco.
With the help of Scott, Erno, Emily and the Utz's housekeeper, Biggs, Harvey and Mick try to evade the evil Goodco Cereal Company and return to their home.
Despite the fairytale elements of the story, its characters are believable. Scott is a regular sixth grader who gets migraines and often hallucinates.
At the beginning of the book, he is going to a new school and is in a class called "Project Potential" for advanced students.
Erno and Emily always compete with each other. Their life is unusual because their foster father gives them "tests", like scavenger hunts, where they follow clues to find answers.
Emily always wins, except when she lets Erno win- on their birthday.
Their housekeeper, Biggs, is the world's tallest man. He protects Erno and Emily and refers to them as "my babies". Biggs is strange and hairy and lives in a tree.
The story begins slowly and takes a while to get going. Yet once I was past the first several chapters, the book kept me on the edge of my seat as the action switched from one character to another.
The book is an interesting read thanks to its fantastical characters. I especially enjoyed reading Mick's old Irish folk tales.
