Code Crisis by Joe Purpura

This fast-paced thriller that follows a lonely gynecologist who risks everything for love and his country will engage you until its final, explosive scene.
Dr. Vince DeLuca would normally take a Tito's straight up with two olives after a ruptured ectopic pregnancy nearly flatlined a patient. Maybe follow it up with a one-night stand to chase away memories of the trauma that's kept his life stagnant for so long.
But when he overhears one of his recovering patients-married to the CEO of a defense contractor-mumbling about "stingers," "revenge," and her affair with a mysterious man named Salaam, Vince's PTSD alights. Sure, it could just be the ramblings of a woman on too much morphine, or she could be talking about the missing anti‑aircraft weapons he read about and a highly sought-after terrorist.
Vince decides to leave it to the FBI, not suspecting that they would send him Carolyn, a drop-dead gorgeous, slightly insane CIA agent who needs his help. Vince is soon thrown into the fray and finds himself both utterly in love and using everything he ever learned in his medical career-including how to clamp a subclavian artery with a zip tie-to help home in on the terrorists' plot, but not before they discover him and come looking for blood.
