The Event Group is faced with an impossible mission in the latest heart-pounding hit from the New York Times best-selling author of Carpathian.

In 267,000 BCE the continent was its own world, untouched by the planetwide catastrophe that ended the reign of the dinosaurs over 65 million years before. A traveler arrives in the jungles of this ancient world who will fight to survive carnivorous creatures in a land never meant for humankind.

In another time and in a land far distant, men and women struggle to recover from the loss of so many of their own in a battle. Inside of this group, Colonel Jack Collins has summoned the best of the best from the most secretive organization in the United States government, the Event Group, to help him in his quest. The new mission is to recover one of their own: to bring home a lost soldier from a world that existed in the distant past.

To accomplish the impossible, Department 5656, the Event Group, will have to travel to a place and time far removed from their own world - almost 300,000 years in the past. The trail to find the technology to accomplish time travel will be ripe with treachery and murder as the group fights to bring home their friend, Captain Carl Everett, a man who was lost in a battle to save the world. This will be a fight that, if lost, will change the very history of the planet and thus our present.
