I spend a lot of time at sea, and do not have much internet content. I have just bought a Kindle Fire 10 HD 64gb with the purpose of saving books to my kindle fire, and reading them on the ship. Unfortunately, all my books seem to be saved to the cloud, and download from the cloud. This will not work when I am out of internet range. I would like to save my books to the Kindle Fire, but cannot see a way of doing this. It must be easy, but I do not find technology easy as I am old.
