A third cover art for the same book from Eric made in western movie vibe.
Early 19th century in what is now Bolivia and Argentina at the start of the South American Wars of Independence to free themselves from Spanish rule. Spain and the Aymara Indios are the two main bands that fight each other. And in the middle of it is Juana (the protagonist), a mother who just wants to keep her children safe, but gets more and more drawn into the conflict.
