I have downloaded the OverDrive App to my Kindle and now I can download digital and audio books free! from my local library, they are on your device for three weeks and then, deleted.
I was told about this at my library yesterday, they support quite a few devices, I am really pleased about this as I pay £2 each time I take a audio book out of the library.
This the App I downloaded
