Here, two moons rule society, and nature outshines science. But just like her own climate ravaged planet, this verdant Earth has a sinister side. Children are rare. Humans must serve a purpose or pay an unthinkable price. Astronomer Zuzi battles this underlying darkness every day - just like Maeve did at home. Both women are fighters, and both face a choice: forge new paths, or save the worlds they''ve always known? Maeve will have to decide, and fast - because she''s fighting for more than just herself.
