Walt Whitman, author of the epic poem "Leaves of Grass," wrote a novel? Lost for 165 years, found by a graduate student, "Life and Adventures of Jack Engle" was written when Whitman was a downon-his-luck housebuilder in New York. A rollicking tale of orphanhood, greed, and adventure, it was published under a pseudonym, serialized in a Sunday newspaper, and forgotten. Republished by the University of Iowa Press, it's a missing piece of American literature with clues to Whitman's masterpiece. Hardcover, 184 pages.
