Hello -

I have a Kindle Touch linked to my Amazon account where I buy my books. My mother has a Kindle linked to her Amazon account. Since I trust my mother, and she trusts me we generally deregister our Kindles and register to the other's amazon accounts to 'borrow' books from each other. It works. When you deregister from her account and reregister to my account all my books and the books of hers I downloaded are there.

Enter Kindle Fire... My sister has a Kindle Fire. I can register my Kindle Touch to her Amazon account and download her books to my device. When she deregisters and registers under my account she can see my books, open then, but once she deregisters they are gone. Is this the inherent nature of the Kindle Fire? Or is there a setting that needs to be changed?
