Courage, 30,000 BC — Bonnye Matthews

It's 30,000 BC. Hiding in a giant mimosa tree, Maru watches her father meet with the leader of a treacherous Andean tribe. Her father, furious that she's followed him, tells her that if he is killed -- something he fully expects -- she must warn their people to flee. The people are prepared; Maru at age seven is not. Her father places heavy responsibility on her because she followed him.
