Planetary geologist Dr. Micah Clarke, his nine-year-old daughter Faye and his assistant Catalina Abril are abducted at gunpoint; forced to join a megalomaniac’s paramilitary expedition down an Amazon tributary ruled by murderous pirates and cannibal tribes. The goal—recover a meteorite capable of providing clean energy for the world. But prehistoric terrors lurk around every bend in the river. Swarms of six-inch titan ants and a seventy-foot Titanoboa tear a bloody swath through the flotilla. Micah is convinced that some unknown intelligence is manifesting these primeval horrors to protect the meteorite’s secrets. To defend his daughter, Micah must battle monsters, pirates and cannibals, all leading to his ultimate confrontation with an ancient force possessing the power of creation, or total destruction… and the doomsday clock is chiming midnight.
