Towson University Assistant Professor Angela Pelster's new book of essays, “Limber”, is a book about trees; from “The Tree That Owned Itself” in Georgia, to “The Loneliest Tree on Earth” which once stood in the middle of the Sahara. But, the trees are often just a starting point for essays that delve into topics ranging from faith to love to language itself. Angela Pelster joins Nathan Sterner in the studio to talk about the book.
