"Among the best books of this or any other year."-Los Angeles Times Book ReviewAmerica's first frontier was not the West; it was the sea-and no one writes more eloquently about that watery wilderness than Nathaniel Philbrick. In his bestselling In the Heart of the Sea Philbrick probed the nightmarish dangers of the vast Pacific. Now, in an epic sea adventure, he writes about one of the most ambitious voyages of discovery the Western world has ever seen-the U.S. Exploring Expedition of 1838– 1842. On a scale that dwarfed the journey of Lewis and Clark, six magnificent sailing vessels and a crew of hundreds set out to map the entire Pacific Ocean-and ended up naming the newly discovered continent of Antarctica, collecting what would become the basis of the Smithsonian Institution, and much more.
