"It has been said that, among the continents, South America will teach it to you: God and the Devil are the same; this last great reservoir of primordial wilderness is at once both Garden of Eden and green sweltering Hell."In the dead of a Chicago winter, a twenty-something middle-school biology teacher, Andie Easter, and six young colleagues, hatch a plan to spend their summer in Brazil, hoping to reverse their meager fortunes by joining a modern-day gold rush on a tributary of the mighty Amazon. Disoriented and increasingly isolated, the treasure hunters stray into the remote domain of three colossal snakes: daughter, mother, grandmother. One by one, under terrifying circumstances, the teachers fall victim to the devastating effects of gold fever and the relentless brutality of the primeval South American jungle. Andie Easter must discover her inner Amazon to avoid becoming prey for the Mother of All Snakes.
