You would think this book would be a fun adventure book to learn about the West. Do not let children read it. The Indians and traders are perverts who trade children as sex slaves. Then the Army comes in and the one of the generals sexually abuses the boys. I'm so upset reading this book. No wonder I had never heard about it. It's just a horrible book. I stopped reading half way through. I'm going to tell the library to pull it from the children's section of books. So, so sad that Nelson messed up a Twain book like this. Also as I skimmed the second half I could see how it was all about promoting Mormonism and finding "Great Salt Lake City".
