Sorry to hear about the long terms illness Joy, but glad you’ve got an escape from it. Yes Kindle books are great as there are always freebies or sales going on.
While I love physical books like you said they take up a lot of space. When I moved house mine took up a lot of space in the moving van. I’ve since got rid of quite a few, but there’s some I simply can’t let go of. Those that I really enjoyed.
