"But if from there you seek the Lord your God, you will find him if you seek him with all your heart and with all your soul." (Deuteronomy 4: 29)

Colonel Katie Green fights to save her Air Force career after a senior-level review board decided to revoke her Top Secret security clearance. Katie's misgivings about just war leads to her clearance kerfuffle because she fears a US preemptive nuclear strike would fail God's litmus test, yet nuclear weapons are her ticket to promotion to general officer. Haunted and challenged by her father's suicide after losing his clearance, she seeks refuge in God's Word.

By day, she engineers a launcher that releases missiles with Mach 4 exit velocity, quadrupling the speed of sound. She earns a Department of Defense patent for her seminal development. General Patricia Moynahan, Katie's sinister boss, races for promotion to major general at the expense of national security, while threatening Katie's rising influence. Equally menacing, a Department of Energy duo, whose nefarious antics upend her best attempt to correct latent launcher malfunctions, casts shadows on Katie's past, present, and future. Both Moynahan and Energy present near insurmountable roadblocks. But Katie believes God's grace is sufficient.

By night, Katie's Bible study teacher and soulmate, Dr. Pete Markham, fuels her confidence by showing why God considered King David a man after his own heart, despite David's bloodstained hands. David clinched God's blessings as he exposed his human frailty. How Katie longs to be a woman after God's own heart. Could she risk defying God without losing his favor?

General Tom Davidson, Katie's mentor and leading Air Force policy maker on all things nuclear, guides her career trajectory that includes the possibility of fighting unjust wars. His support rivals the relationship she sanctions with God—a troubling dilemma defined by Davidson's power to ensure her promotion to general officer.
