Mac Slater is an inventor. He’s never really thought of himself as cool. Sure, he and his best friend, Paul, do all kinds of fun and crazy stuff: They built a flying bike and lots of other wild, fast-moving inventions. But when the creators of Coolhunters approach him and offer him a job hunting cool for their massively popular website, Mac thinks they're crazy. Now he’s pitted against the most popular girl in school and all eyes are on him. Is Mac Slater cool? Or will he crash and burn in front of millions of kids across the world?
