I just finished “Nuclear War: A scenario” and this left me extremely anxious, please recommend me a good book to forget about the last one I read.

I just finished Nuclear War.

It left me anxious and scared. It's an incredibly disturbing book that shows a scenario (albeit for me not very realistic because the people in the book behave like machines and nobody stops to think) of apocalyptic purputions.

Now I want to read a book that will wipe off this "unsettling" feeling.

Any recommendations?

I love sci Fi, fantasy and books similar to Nuclear War. I've read most of the classics of Sci Fi and Fantasy but haven't read new fantasy or sci Fi books released in the last 20 years.

Thank you.
