I know I prefer to read cookbooks in a real sense, but there are some interesting cookbooks available on kindle for a dollar or two that I also enjoy filling the niche like Thai, Chinese takeout, Indian, etc. Here is a link to a Stephen Raichlen BBQ book for a dollar that will lead you to be able to browse a number of others if you wish.
