Dax Masters has everything he could wish for—great friends, a good handle on 7th Grade, and a science community to run. As head of the Earth Moves project, Dax has inspired other kid scientists from around the world to share their observations. His schedule is full, but that doesn’t stop him from signing up for a new extracurricular class, Environmental Studies.
Dax hopes he can sail through the new class by using Earth Moves to expand on what he’s learned about tectonic plate movement. But when a new problem presents itself, Dax can’t ignore his instincts. Once again—and with the help of his classmates—Dax has identified a global crisis that others have missed.
This time, though, Dax has to prove to himself that he has what it takes to find a solution. But first, he has to figure out what is wrong with the oceans. Amid the swirling changes to the planet and to himself, Dax finds himself searching for answers to a problem that, if unsolved, could be disastrous for the planet.
