I guess, since I already paid a lot of attention to trees, and already considered them more or less to be people, and was already familiar with some of the research into how trees communicate with each other, it didn't impact me as much as some other readers.

I also really disliked the fact that Powers has a large cast of characters, whose stories span a century and most of a continent, and not a single one of them was Black or Indigenous. To not mention the Indigenous peoples of the Americas in a book that's about the nature and ecology of North America seems disrespectful at the very least. Then again, if Powers were to mention Native Americans, he would have to grapple with the fact that many Native American societies were quite successful in consciously stewarding and co-evolving with trees and other species, which would then detract from his anti-human message.

Much of Powers' interesting information about tree science can be found in "The Hidden Life of Trees" by Peter Wohlleben (note, he has the same initials as the tree scientist character), so, if that's what you're after, maybe read that first.
