Gil Martins, an agent with the FBI's Domestic Terrorism Unit in Houston, confronts the violence generated by extremism within our nation's borders every day. But when Gil discovers he played a key role in wrongly condemning an innocent man to death row, it shakes his faith-in the system, in himself, and in God-deeply. His problems become more than personal as things heat up in Houston. A serial killer terrorizing the morally righteous turns out to have religious motivations, upping the case from homicide to domestic terrorism. A number of prominent secular icons die or are grievously injured abruptly and under suspicious circumstances, the latest of which is a New Atheist writer who's fallen into an inexplicable coma.
