What would you sacrifice to bring to light the greatest discovery in human history?

Quentin Darnell was only a boy when his anthropologist parents were overcome by a professional failure so crushing it led to his father’s eventual suicide. Now a schoolteacher, he’s looking for answers and senses they can only be found in the wild terrains of Indonesian Papua. He leads his wife, son, and six students on an educational expedition in search of the world’s most pristine environments and isolated aboriginal tribes. But political unrest is brewing, and when disaster strikes, Quentin is faced with a loss so unthinkable the dark mysteries of the past quickly become irrelevant. Trapped in a vicious fight to protect the ones he loves, Quentin is on the brink of discovering a secret with the power to save lives and change the destiny of humanity forever.
