So, I’m trying to find a book that I read but haven’t finished. I have very little clues.

I don’t remember the name of the book. It’s not a mainstream book. It’s a sci-fi, and I think it had some mad scientist in it, not sure if a main or somehow related to main character, and its background was in some other planet, It has three parts short stories in one book. I think this book was pretty old, maybe from 90’s or even before. I don’t think it was from 2000’s. I finished reading the first two but not three.

Thanks!
