Novelist Richard Powers lives in a house perched on a hillside, just on the edge of the Great Smoky Mountains National Park. "It's very much a tree house," he says with a laugh. "That's why I live here."
His latest book, The Overstory, brought him to the old growth forests of Tennessee. The novel follows the lives of nine different people, all determined to save ancient trees from destruction. Their lives become entwined as they fight to save virgin forests, with unforeseen consequences.
