Isaac Asimov’s robot books form a somewhat confusing and internally contradictory, but overall fantastic and important corpus of science fiction. One of the Asimov robot books is on sale right now super cheap in Kindle format: The Caves of Steel (The Robot Series Book 1) for $1.99.
Referring to Wikipedia (so get mad at them, not at me, if this seems wrong to you) the robot series of books (not counting short stories) in order of the stories themselves runs something like this:
The Caves of Steel (The Robot Series)
The Naked Sun (The Robot Series)
The Robots of Dawn (The Robot Series)
No need! I have ALL his books and read at least twice and still have the paperback books in A1 condition in my very large library. I like most of Asimov’s stuff cuz he has a a couple far out SciFi points but other than that it is all about science.
This is why you need the Kindle edition. You should not be reading original paperbacks, they are worth too much!
