A Door Into Ocean – Joan Slonczewski (1986)

Imagine an all-female ocean world where communication is biology and war is unthinkable — until outsiders arrive.
Slonczewski’s A Door Into Ocean is one of the smartest, strangest, most compassionate pieces of science fiction ever written. It’s a blend of ecological philosophy, linguistic invention, and feminist worldbuilding decades ahead of its time.
No space battles here — just intellectual warfare disguised as empathy.
