I have just replaced my partners kindle with a new one and the books I have bought to have appeared. However, they have not appeared on mine which up until a couple of days ago was working fine. Can anybody suggest anything?
yes, go to your account on the Amazon website and log into your Content & Devices page (under the upper right menu on every Amazon webpage). Check and see that the books are there, and if they are use the Actions button [...] to send them to your device. Books only automatically are sent to one kindle, all other kindles registered to the account have to be downloaded separately.
