Earthsong (The Native Tongue Trilogy #3) by Suzette Haden Elgin
Originally published in the 1980s, the Native Tongue trilogy is a classic dystopian tale: a testament to the power of language and women's collective action. In the stunning conclusion to the series, Earthsong imagines a completely new way of being.
The interstellar Consortium of Planets has forsaken the irredeemably violent Earth, condemning the planet to economic and ecological chaos. As the Consortium prepares to euthanize the planet, women freedom fighters are offered one last chance to correct men's brutal nature and stop the planet's annihilation.
In the final book of the Native Tongue trilogy, female linguists must once again come forward to ensure the survival of humanity.
