Former CIA agent turned evangelical pastor John Cross is busy caring for the small community of believers he ministers to in Virginia. Journalist Christine Lewis is busy with the demand for her talents from top news agencies in New York City. Neither has any time left for their relationship, which began eight months before when they paired up to prevent the detonation of a chemical bomb in the nation's capital.

But when Christine hears that her stepbrother has been arrested for murder in Texas, they team up again to discover the truth about the crime. Untangling a web of conspiracy, the couple finds themselves in the center of another dangerous situation-and in trouble far deeper than they expected.

With an assassin on the loose, a trusted colleague acting as a double agent, and unreliable artificial intelligence connected to mercenaries who have Cross on their hit list, these two may not get out of the Lone Star State alive.
