Rule #1: Never trust your wish guide. Facing the worst day of his life, 10-year-old Max hires Mylo, a young wish guide with a set of magical, world-bending tools ... and an outrageous plan! Afraid of your evil music teacher? No sweat! Just one twist of the wrench, and you'll be off playing video games until the end of rehearsal. Hate Dad's nasty sushi? Try chocolate! Bored of washing the car? There's a tool for that, too. At least that's how 10-year-old Mylo pitches his "World Repair Service" to Max. Unfortunately, Mylo isn't really a wish guide. He has no training. He hasn't even read the instructions! It isn't long before Mylo's excessive 'twists' cause big problems. Flying cars. Lava in the streets. Then the music teacher Max begged to avoid-the cruelest man in the universe-becomes a real-life supervillain: an eight-foot-long, man-eating piano bent on world domination! Max has never felt so afraid in his life. But when an evil orchestra kidnaps his sister, Max must finally confront his arch-nemesis, live on stage, in the biggest, strangest, most epically dangerous concert in Earth history. Can Max pull it together for one last performance-or will he become the hungry piano's next meal? MYLO AND MAX BREAK THE WORLD is an action-packed tale featuring music, magic and sibling rivalry, with loads of laughter and a spectacular, feel-good finale.
