Academic publisher Routledge publishes a LOT of books free on Kindle and sometimes there's some interesting looking books there. Just picked up "De-mystifying Translation: Introducing Translation to Non-translators" and "The Routledge Handbook of Refugee Narratives" for free. You can narrow down categories on the left hand side of the page
