Haley-database developer, CIA operative, and multiple personality-is engaged to Willi Mayers. A violent act makes her return home, then her father is murdered. Haley's alter ego emerges, but, after Haley shows an assassin mercy, ends their arrangement. Later, the duo begin work on a Tribulation Tracking System. On the team is Patricia Candor, a born again Christian. Seeing her faith makes agnostic Willi open to Christ, a decision atheist Haley frets about. When the team is attacked, Willi can't defend herself, so Haley sends her to the CIA's Farm for training. Later, as women are abducted, Willi deduces the kidnapper is guided by Revelations' Seal, Trumpet, and Vial judgments. Also, a cryptic message is left at churches - the only way to the Father is through the sunset of Christianity. After Al Qaeda recruits MS-13 to commit terrorist acts, an enraged Willi renounces God and plans to execute all involved. Haley must now deal with two mass murderers and a woman he no longer trusts.
