The Overstory by Richard Powers is different from any novel I’ve ever read. It’s experimental in the sense that it is composed of multiple tangled stories, much like the canopy of a forest, which is appropriate since it’s a book about trees and how we relate to them. “A book about trees” doesn’t do it justice though, since that may give you the impression that it’s slow and boring, which it is not. On the contrary, the best adjective I can think of to describe the writing is crisp and fresh, like a budding branch in spring.
