Rose Eagle - Joseph Bruchac

A novella prequel to Joseph Bruchac's Killer of Enemies, in which Rose Eagle experiences the immediate results of the apocalypse that sets everything in motion.
In the Black Hills of South Dakota, seventeen-year-old Rose Eagle of the Lakota tribe is trying to find her place in a post-apocalyptic world.
Before the Silver Cloud, the Lakota were forced to work in the Deeps, mining for ore so that the Ones, the overlords, could continue their wars. But when the Cloud came and enveloped Earth, all electronics were shut off. Some miners were trapped in the deepest Deeps and suffocated, but the Lakota were warned to escape, and the upper Deeps became a place of refuge for them in a post-Cloud world.
In the midst of this chaos, Rose Eagle's aunt has a dream: Rose will become a medicine woman, a healer. She sends Rose into the Black Hills on a quest to find healing for their people.
Gangly and soft-spoken, Rose is no warrior. She seeks medicine, not danger. Nevertheless, danger finds her, but love and healing soon follow. When Rose Eagle completes her quest, she may return with more than she ever thought she was looking for.
