"In the dark of night, a team of assassins attack Delphi operative Zane Watson in his own home. Driven by revenge and the need for answers, Zane leads the Delphi team on a global chase that ends in Jerusalem, where they discover the dead body of archaeologist Solomon Glaser. Evidence gathered at the scene suggests Glaser was tortured and killed for information only he possessed.
With help from a woman the archaeologist entrusted with his secrets, Zane and fellow operative Amanda Higgs begin to unravel a conspiracy of epic proportions: an ancient order is responsible for Glaser's death, and the group will stop at nothing to find the location of a place that some call the Chamber."
