Robert Sullivan, the New York Times bestselling author of Rats and Cross Country, delivers a revolutionary reconsideration of Henry David Thoreau for modern readers of the seminal transcendentalist. Dispelling common notions of Thoreau as a lonely eccentric cloistered at Walden Pond, Sullivan (whom the New York Times Book Review calls “an urban Thoreau”) paints a dynamic picture of Thoreau as the naturalist who founded our American ideal of “the Great Outdoors;” the rugged individual who honed friendships with Ralph Waldo Emerson and other writers; and the political activist who inspired Martin Luther King, Jr., Mahatma Gandhi, and other influential leaders of progressive change. You know Thoreau is one of America’s legendary writers…but the Thoreau you don’t know may be one of America’s greatest heroes.
