Richard Powers & Bill McKibben

Richard Powers is the Pulitzer-prize and National Book Award-winning author of twelve novels, including Orfeo, The Echo Maker, and The Time of Our Singing. The Overstory, Powers most recent novel, is a sweeping, impassioned tale of activism and resistance that is also a stunning evocation of – and paean to – the natural world. The Overstory unfolds in concentric rings of interlocking fables that explore the essential conflict on our planet: the one taking place between humans and nonhumans.

Bill McKibben is an author, environmentalist, activist, and the co-founder of 350.org, an international climate campaign that works in 188 countries around the world. His 1989 groundbreaking book, The End of Nature – issued in dozens of languages and long regarded as a classic – was the first book to alert us to global warming. He’s gone on to write a dozen more books, most recently Falter: Has the Human Game Begun to Play Itself Out? The Schumann Distinguished Scholar in Environmental Studies at Middlebury College and a fellow of the American Academy of Arts and Sciences, he is the recipient of the Right Livelihood Prize, the Gandhi Prize and the Thomas Merton Prize, and holds honorary degrees from 18 colleges and universities.
