A Peoples History of the United States* by Howard Zinn is a classic revision of American History.
The Last Days of the Sioux Nation (Second Edition) by Robert M. Utley is a classic, but not necessarily the one book you’ll want to read about Native Americans of the northern Plains. But I put it here because it is currently dirt cheap on Kindle, and if your library does not have this 1963 title you may want to grab it up. I would recommend as a first read in this area of culture and history the recently published tour-de-force Wounded Knee by the amazing historian Heather Cox Richardson. Not on sale at this time but worth it.
I should mention that right now you can get some great deals on the Paperwhite Kindle.
edited by John Kilma, with modernized fair tale stories by Gregory Maguire, Susanna Clarke, Karen Joy Fowler, Charles de Lint, Holly Black, Garth Nix, Kelly Link, Peter Straub, Neil Gaiman, Patricia Briggs and others.
by John Joseph Adams.
by Terry Pratchett. Involves trains.
by good Will Hunt. Involves caves, subway stations, bunkers, and such. I don’t know the book, stumbled across it, looked interesting.
