From racing across glaciers in Greenland and flying in a super fancy solar-powered jet to Hawaii, to visiting the Great Barrier Reef off the coast of Australia and hanging out with a robot named Leo, twelve-year-old genius Max and her friends live for adventure. Whenever there's a problem to solve, the kids work better together. So does an evil group of the rich and powerful, who will do whatever it takes to split the kids up -- even as the planet is changing before their eyes. Max has one more surprise in her playbook, and if she's going to pull it off, she needs her team around her. Whoever said that kids can't save the world?
