Walden and Civil Disobedience

Well on Saturday I was at Barnes and Noble looking for a new book and I couldn't find one so my dad suggested Walden and Civil Disobedience. The author is Henry David Thoreau. I haven't started reading it yet but I looked at the summary thingy on the inside cover. It is basically two stories. Actually one of them is an essay or something that the author wrote about civil disobedience. He wrote the essay about his experience of being imprisoned for refusing to pay Concord's poll tax and the citizens duty to watch over the government. The other part was about his experience in Walden. The book is supposed to be a classic so it should be ok
