The Unincorporated Man

Somewhat lesser-known sci-fi novels I read in the past: The Unincorporated Man (and three sequels) Cross between science fiction and fantasy: Harry Potter and the Methods of Rationality ("HPMOR") - the premise is that Harry Potter is raised by a good aunt and uncle, and is taught the Scientific Method and so he uses that when encountering magic. Old Man's War (and sequels) by John Scalzi Redshirts by John Scalzi Science-reality: Surely You're Joking, Mr. Feynman! Ra by qntm There is no Antiemetics Division by qntm

The Unincorporated Man (Ender's Game too, but haven't read the sequels, but I also recommend Ender's Shadow - a parallel novel from a different character's perspective.)

The Unincorporated Man by Dani Kollin & Eytan Kollin. It's a sci-fi set a couple hundred years in the future where everyone is incorporated at birth. Just like you can own shares in a company, you can own shares of another person. It's my second favorite novel. It has some interesting ideas. Ender's Game by Orson Scott Card. Don't let the movie fool you. The book is very good. It was at one point it was on the suggested reading list for the United States Marine Corps.
