Query: The Grandfather Trees and All of Us

This is, as the title says, a book about a tree. From the opening pages, it is an extraordinary story about an amazing tree. The author focuses, evokes, and clarifies--much like the tale of a single person's life can--huge and complex historical events otherwise lost in the vastness of time. Jacket blurbs are usually written to hype a book. In this case, the subtitle: "A True Story of Myth, Madness, and Greed" is completely accurate.This is a very special, important, and deeply moral book about all of us and the Earth today.
