A Door Into Ocean

A Door Into Ocean, by Joan Slonczewski

This 1986 novel has become known as a minor classic of speculative fiction; it is SF at its most socially provocative. What happens when an all-female, pacifist society with highly advanced biotechnology is invaded by a militaristic neighbor which decides to colonize and exploit their peaceful ocean world? Slonczewski doesn't opt for easy answers, as good people on both sides try to find the best solutions to the conflict. This is something we can identify with strongly, despite the strange setting of the story.
