About This Book
The thick, humid air of the Amazon jungle wraps around you, filled with the calls of unseen creatures and the rustle of leaves. From a tiny plane, Fred watches the endless green canopy stretch below, dreaming of adventure and discovery. Suddenly, the plane crashes, and the jungle’s mysteries become a thrilling, dangerous reality — but the biggest surprise is that they might not be alone.
