The Pathfinder, or The Inland Sea, by James Fenimore Cooper, is a historical novel that came out for the first time in 1840. The book is one of the Leatherstocking Tales, which is a set of books about a frontier hero named Natty Bumppo. Cooper wrote The Pathfinder, which is the fourth book about Natty Bumppo and the third in order. In the late 18th century, Natty Bumppo, also known as the Pathfinder, leads a group of British troops and a young woman named Mabel Dunham through the wilderness to Fort Oswego on Lake Ontario. Along the way, they meet Native American groups and have to make their way through dangerous waters. The Pathfinder is an adventure story about being brave, being loyal, and being able to stay alive when things are dangerous. Cooper's writing style is known for how well it shows the natural world and the people who live in it, as well as how it shows Native American culture.
