A construction project threatens to carve a 220-mile walled corridor through the heart of central Maine's woods and wetlands, destroying vital habitats and siphoning billions of gallons of water. The project manager, Harold Brown, is poised to break ground.
Opposing him are Chris Atwater, a pragmatic non-profit coordinator working within the system, as well as Albert Lesiak and AJ Blasius, self-styled earth warriors who prefer direct action. Their conventional efforts seem doomed to fail-until Cosme Esperanza arrives.
A mysterious healer hiking the Appalachian Trail, Cosme tells them there may be a way to render Harold more receptive to the voices of the earth, and they dare to think there may be hope for humans yet.
