A young American couple conducting an aerial survey of central Africa is shot down by hostile militia in a dense region of the Congo. With their attackers in pursuit, Brandon and Samantha are pushed deeper and deeper into the forest, to a place so terrifying that even the local Mbuti refuse to enter. The pair soon discovers another party is risking the dangers of the jungle, seeking a rare flower with vast medical potential. As the two groups combine forces against the genocidal militia, the Blood Forest holds them all with a secret that is more complex and sinister than any of them realize. "This forest has a pulse. It beats in my chest. I can see it in the eyes of the beasts. Together, we move to this rhythm. It calls to us. It calls for blood."
