Edward Gray published The Making of John Ledyard: Empire and Ambition in the Life of an Early American Traveler with Yale University Press.  "Daring, ambitious, and theatrical, John Ledyard seems to step out of a great eighteenth-century novel into this vivid and revealing history. Following Ledyard's clues, Edward Gray draws readers through a compelling and global story of ambition, adventure, and empire."—Alan Taylor, author of The Divided Ground: Indians, Settlers, and the Northern Borderland of the American Revolution.  “Ledyard’s career opens up the entire world, in the most literal sense. His is a really grand story, one that transcends all sorts of conventional boundaries.”—Edward Countryman, Southern Methodist University
