The Terraformers by Annalee Newitz

From science fiction visionary Annalee Newitz comes The Terraformers, a sweeping, uplifting, and illuminating exploration of the future.
Destry's life is dedicated to terraforming Sask-E. As part of the Environmental Rescue Team, she cares for the planet and its burgeoning eco-systems as her parents and their parents did before her.
But the bright, clean future they're building comes under threat when Destry discovers a city full of people that shouldn't exist, hidden inside a massive volcano.
As she uncovers more about their past, Destry begins to question the mission she's devoted her life to, and must make a choice that will reverberate through Sask-E's future for generations to come.
A science fiction epic for our times and a love letter to our future, The Terraformers will take you on a journey spanning thousands of years and exploring the triumphs, strife, and hope that find us wherever we make our home.
