Robert A. Heinlein: Stranger in a Strange Land - Everyone should read this one The Moon Is a Harsh Mistress - Revolution made fun. Starship Troopers - A fun war book and a different slant on
politics. Citizen of the Galaxy - One of the best Heinlein
juveniles. This book really has a soul. Friday - It's fun. It's got love, and violence, and
politics, and superhumans, and it alwats keeps moving. Job: A Comedy of Justice - Turns religion on it's head. Time Enough for Love - It's a very very long book. It's
really just a set of intertwined stories about one man and his life,
all variation on the theme of love. It's got some realy good stuff in
it, and don't feel bad about skipping parts of it. Glory Road - A fun fantasy-adventure story that ends with
an morose overdose of reality.
Larry Niven: Ringworld - It's worth reading for the concept alone. The Ringworld Engineers - The sequel: almost as good. Neutron Star (a collection of short stories) - Study your
mechanics, then try and figure out the first story before the hero
does. The Mote in God's Eye (with Jerry Pournelle) - Heinlein
called it "possibly the finest science fiction novel I have ever
read." If sci-fi isn't your thing, this is the only Niven you
have to read. The Gripping Hand - The sequel.
