Just finished reading this book for the second time. I may master it in another 10. Undoubtedly the biggest book I have ever read - as complex and rich, as giving and demanding, as damning and revelatory, as the overstory and understory themselves. Reading it may not change your life, but it will change the way you look at it, the way you look at it in its natural context, and, perhaps, the way you chart it going forward.
