A #1 New York Times Bestselling Author
A United Nations relief team in a small village in the Congo makes an alarming discovery. An unknown force is leveling the evolutionary playing field. Men, women, and children have been reduced to a dull, catatonic state. The environment surrounding them - plants and animals - has grown more cunning and predatory, evolving at an exponential pace. The insidious phenomenon is spreading from a cursed site in the jungle - known to locals as the Kingdom of Bones - and sweeping across Africa, threatening the rest of the world. To head off global catastrophe, Sigma Force must risk their lives to uncover the shattering secret at the heart of the African continent - a truth that will illuminate who we are as a species and where we may be headed . . . sooner than we know.
