Anyone know how to share amazon primebooks with someone?

I have Amazon prime and have access to a few free books on prime reading.I want to share them with someone.I have aded them to my household,they accepted the invitation,i press share beside a book,and i've tried to send/share it after i put it in my library but get nowhere.
There's nothing appears in her Amazon account and if i try to send it by just pressing 'share' beside the actual full version of the book she just gets sent a sample of the book??

Has the new person in your Amazon household added a payment card on to her account?

I had this when I wanted to shared my Prime account (in my case to share Amazon Prime Video) nothing was visible to the invitee until they added a shared payment card - you can see their card details - they can't see yours. I guess it's to prove that you know and trust the person in your household.
