Tor.com has always been a favorite of mine, and when they started publishing novellas I bought a few. I didn't read any, since I'm a very busy man and all, but I bought them and that has got to count for something!
I finally decided to read All Systems Red, and on one hand I wish I had read it sooner but then again if I had the wait for the second novella would be even longer.
The main character calls itself Murderbot, but I don't want to talk too much about it since that might give away some things that are better off discovered while reading. I will say that Wells manages to paint a very comprehensive world in less than 200 pages. I know there's lots more to discover in this universe and I hope that she is working on a full raft of books!
The ebook is super cheap, and it isn't a big commitment of time so just read it already.
Who should read it: If you like introspective robots, this is the book for you!
Would I read it again: Sure! Though I'd rather read the next one.
