What the Bones Say by Tonya R. Moore
Niara’s people inhabit a village within a walled enclosure on an alien planet. To carve out a future for humanity, she must disobey their alien benefactors and venture beyond the wall. She joins forces with Wendi, tribal queen of the eastern village. The two women forge a bond stronger than blood as they uncover the secrets of their buried history and incite the wrath of an advanced alien force.
