Michael's first day in fifth grade is not going well. A new school is bad enough, but the teacher has partnered him with two extremely weird kids. Bob and Jennifer tell Michael that they are Spaceheadz from another planet and that they need his help to save the world. They explain that Earth is in danger of being turned off, depriving the interstellar civilizations of our tasty TV and radio waves. Led by Major Fluffy, the class hamster and mission commander, they must recruit 3.14 million (+1) Earthling brainwaves to join in one giant SPHDZ wave to keep the planet online. However, Agent Umber of the secretive Anti-Alien Agency is on their trail. Umber, the most inept spy since Maxwell Smart, hopes that Michael can lead him to the ETs. Michael wants to save the Earth, but does that mean helping the Spaceheadz or turning them in? As in Scieskza's "Time Warp Trio" series (Viking), comically twisted contemporary cultural references abound. The young aliens speak primarily in TV advertising slogans, which fit remarkably-and hilariously-into the dialogue. Real commercial products, from George Foreman grills to Charmin toilet tissue, are put to exotic extraterrestrial uses. The intriguing book design includes chapter headings in English and SPHDZ characters, occasional white-on-black pages, and SPHDZ "stickers" scattered throughout the text. The black-and-white cartoon illustrations are often integrated into the text layout, giving the book a graphic-novel feel. Four creative, well-designed websites contribute important information to the story. Science-fiction fans with a taste for off-the-wall humor will be eager to join the SPHDZ movement.
