What language are you reading them in? What's the current book about?
English. I tried Spanish but my Spanish isn't good enough. The last one I read is about an ageing colonel waiting for a letter than never comes while being pushed around by everybody.
Now rereading Isaac Asimov's The End of Eternity. I've read it a few times before but really just felt like reading it again.
I have all the Asimov I can find, except for some of those enormous textbooks.
I have two, but it does not take long for me to bog down in the quicksand of Biochemestry, etc. Math is easier and very helpful.
Wish I had read these scripts when I was designing horn loaded speakers.
I keep reading and looking things up.
I can not say I have enough time left on this Earth to get it all.
Asimov was a rare mind.
All of his fiction is more than worth a read!
