It is 1804, the year that Meriwether Lewis, William Clark, and the Corps of Discovery set out for their now-legendary exploration of the Louisiana Purchase, departing St. Louis to travel across the continent to the Pacific Ocean and back. This fictionalized biography of Lewis and Clark s journey introduces Seaman, a 150-pound Newfoundland dog and unheralded member of the Corps, to young historians. Seaman travels the long journey with the Corps, playing a key role in the expedition s success by catching and retrieving game, and protecting the team from wild animals and hostile Native Americans. Gail Langer Karwoski s thrilling account of Lewis and Clark s expedition with the Corps of Discovery, Seaman, and eventually Sacagawea, full of accurate details drawn from Lewis s own diary entries, will draw readers into one of the most exciting chapters in American history.
