When three children endure separate climate change disasters--a wildfire in the California woods, a close encounter with a hungry polar bear in Canada, and a massive hurricane in Florida--they emerge from their experiences committed to changing the world.

California: Akira Kristiansen is driving through the mountains with her mom when a wildfire sparks-- and in just moments, Akira and her family have to evacuate. But which way is safe with fire all around them? Churchill, Manitoba: Owen Mackenzie is running a tour for travelers who have come to see the polar bears. When Owen and his friend George see a bear too close for comfort, they end up in a fight for their lives. Miami: everyone's saying this could be The Big One, but Natalie Torres and her mom don't have anywhere to run to. When floodwater rushes through the house, Natalie is dragged out into the storm. Swept up in the global effects of climate change, each is struggling to survive their individual disasters-- unaware they are more deeply connected than they could ever imagine. -- adapted from jacket
