The climate crisis is here, and no refuge is safe. In the late 2050s, Henry seeks safety in Sediment Valley, an Appalachian retreat promising peace, prosperity, and a place to bake his delicious sweets. But the corporate powers of SustainAble have other plans for Sediment Valley and the geologic power it hides. Henry soon meets Colson, a reserved butler for the founder of Sediment Valley, and Brisa, a tech genius with an outgoing spirit. Unbeknownst to Henry, both Colson and Brisa have concealed their motivations for leaving the violence of the outside world. When they discover the true, terrifying plans for the valley and its inhabitants, Henry, Colson, and Brisa must learn to trust one another to save themselves, their loved ones-and the world. Three isolated heroes face impossible odds. Can they work together to liberate the valley? Or is it already too late to act? A Valley to Harness welcomes readers, new and returning, to the speculative future of The World's Revolution.
