fe and daughter, special ops agent Cody Willis struggles to cope with his overwhelming grief and, as a result, is sent on temporary leave from his work--one of the only places that ever felt like home to him.

No longer knowing who he is, Cody is forced to pick up the pieces. But when his sister, Tessa, is kidnapped and forced to lead a top-secret job as the head of a research team in Peru, working to uncover the many secrets of the Nephilim--a race of ancient giants once thought to have dominated our lands--Cody realizes that perhaps leaving behind the life of special ops isn't as easy as he thought. With the help of several of his fellow special ops agents, Frank, Val, and Tom, the four men race across the world in order to save one of the last people Cody thinks he has left as the clock quickly ticks down the time they have to do so.
