A History of Wild Places by Shea Ernshaw

A mystery within a mystery. A psychic people finder goes looking for  a children's book author and ends up at a commune called Pastoral.  The focus then shifts to years later and the inhabitants of Pastoral.  They believe that their haven within the tree line keeps them safe and free of the disease and danger outside the tree line.  They live off the earth and the skills of their community without any of the modern conveniences.  is there a bogeyman past the woods? Is there anything left out there? Are any of the people in Pastoral immune to the disease in the trees and have some of them made it past the tree line? The dynamic between Theo, his wife Calla and Calla's sister is edgy.  I won't say more for fear of spoiling the book.
Scary, futuristic and a sure bet for fans of Grimm's fairy tales, LEAVE THE WORLD BEHIND, and SORROWLAND or other cult stories.  4 stars
