The Middle of a Wish 

It is the middle of the 21st century and global temperatures have risen by 2 degrees Celsius. Nomadic bands of climate refugees roam the Earth. Follow one such group from the west coast of North America as they journey toward the Heartland, a region rumored to have underground cities, vast wind farms, blockchain banking, and a revived internet. But first, they must cross the newly formed Valley Sea. For those who make it to the other side, a new world awaits.
