Fire. Ice. Flood. Three climate disasters. Four kids fighting for their lives. Alan Gratz shines a light on our increasingly urgent climate crisis while spinning an action-packed story that will keep readers hooked--and inspire them to take action.

In the Sierra Nevada mountains of California, Akira and her horse struggle to escape a massive wildfire.

In Churchill, Manitoba, Owen and George flee starving polar bears that have been stranded on land by melting sea ice.

In Miami, Florida, Natalie fights to keep her head above water–and save her neighbor’s dog–as her city drowns in a hurricane.

Though they live thousands of miles from each other and face disparate challenges, Akira, Owen, George, and Natalie will come to understand they are more deeply connected than they ever could have imagined–and in ways that will change them and, possibly, the world.
