Thank you for the update. I am not aware of any way to do that legally.
For this reason, I am opting out of the question and allowing another expert the chance to help.
The next expert will see all that is on this page, so there will be no need to repeat anything.
When another expert picks this up, you will be notified by email.
Thank you for your patience.
Hi my name is Shaw aka Dr.Fix-It , Your online expert ready to assist you... Does the old Kindle still come on?
If the books were manually loaded on the Kindle, then me be able to connect it via usb cable and transfer the content to your computer.
Otherwise if the Kindle is registered to your friend, then the content is only linked to that specific account and may not open on a Kindle not linked to the same account.
Please let me know and will do my best to further assist, thanks
