Julian may all the saga of the pliocene excil execept the
many colored land. I have that one.
These are a few. I know they’re all over the place but I’ve been reading for 60 years. Some of them are like new all over again. I can’t remember the details but just that the book was great.
None of these titles look like they are old enough to have been passed off into the public domain.
It would be significant legally via copyright to do anything other than a private reproduction. That is, you record it yourself or have an AI program do it for you. And do not put it online. I do not think there are any other options if the publishers are refusing to create audio versions of these works.
I would recommend not breaking copyright law. That’s bad for one’s health.
