There are a ton of free books on
amazon. Many of the classics. I am currently re-reading little woman. The books to purchase vary from a few dollars to $9.99 or so for new bestsellers out in hardback. I usually sort by the most recently downloaded choice. This usually shows you new books that are free, as these are what people are downloading. Sometimes a publisher will make book one in a series free on the hopes that if you like it, you will like all of them. You can also sort by price and this will bring free books to the top and it will take you a while to page through the many choices. Another option is that you can sort on NY times bestsellers.
