In his 2019 Pulitzer-Prize winning novel, “The Overstory,” Richard Powers imagines a world where only a few acres of virgin forest remain on the continent. A group of strangers band together to protect those few remaining trees, and in the process, discover the trees are communicating with each other. Powers’ new novel, “Playground,” turns the same eye to the planet’s oceans. As he tells Kerri Miller on this week’s Big Books and Bold Ideas, his hope is that the power of storytelling will animate humans to behold the sea with fresh wonder — and act to preserve it before it’s too late. “These last three novels of mine are attempts to find ways of telling stories that challenge that separateness or sense of entitlement,” he says, “that sense that we are the essential and perhaps the only interesting game in town and that everything else is a resource for our project.” Guest: Richard Powers is the author of fourteen novels, including “The Overstory,” “Bewilderment” and “Orfeo.” His new book is “Playground.” Subscribe to Big Books and Bold Ideas with Kerri Miller on Apple Podcasts, Google Podcasts, RSS or anywhere you get your podcasts.
