Describe the setting in "The Adventures of Huckeleberry Finn".
This depends largely on what part of the book you are reading since Huck is at the Widow's house, Pap's cabin, the cave he and Tom found, the island where he runs into Jim, on the river, at the Grangerfords' house, conning people with the King and the Duke, and finally at Tom's aunt and uncle's house. There are many settings in this novel.
He does spend most of his time on the river and there is much page space spent discussing the night and the stars, etc. The river is quiet and peaceful. At night the stars are vivid like flashlights sparkling and Huck can hear the voices of the people looking for him over the water. Huck feels free here, and he enjoys this life where there is no one to tell him what to do or not to do, how to live, or how to behave. This is especially important since the novel was written for post-Civil War readers where Huck, a white boy, is free to travel and go into the towns for food and information but his travel companion, Jim, is not. He must stay on the raft and hide in order to be safe from bounty hunters who would take him in as a runaway and collect the finder's fee. There is also no one to preach religion at him all day which was a problem at the Widow's house.
