The warm fall day starts like any other at the Center--a women's reproductive health services clinic--its staff offering care to anyone who passes through its doors. Then, in late morning, a desperate and distraught gunman bursts in and opens fire, taking all inside hostage. After rushing to the scene, Hugh McElroy, a police hostage negotiator, sets up a perimeter and begins making a plan to communicate with the gunman. As his phone vibrates with incoming text messages he glances at it and, to his horror, finds out that his fifteen-year-old daughter, Wren, is inside the clinic. But Wren is not alone. She will share the next and tensest few hours of her young life with a cast of unforgettable characters: A nurse who calms her own panic in order save the life of a wounded woman. A doctor who does his work not in spite of his faith but because of it, and who will find that faith tested as never before. A pro-life protester disguised as a patient, who now stands in the cross hairs of the same rage she herself has felt. A young woman who has come to terminate her pregnancy. And the disturbed individual himself, vowing to be heard.

Gideon Davis, whose behind-the-scenes negotiating skills have earned him the role of peacemaker in conflicts around the globe, knows more about hush-hush discussions in Capitol corridors than he does about hand-to-hand combat. But his more practical, tactical skills become vital when he's called upon by family friend and government big-wig Earl Parker to bring in a rogue agent - Gideon's own brother Tillman. Gideon is transported from a DC awards dinner to the jungles of the oil-rich nation of Mohan, where Tillman has promised to give himself up. But on his arrival the plan goes immediately awry. Gideon must evade hostile locals to make his way to The Obelisk - a multi-million-dollar, state-of-the-art oil rig that has been seized by terrorists. Both Tillman, who doesn't seem to have surrender in mind, and Earl Parker are aboard the ill-fated rig - Tillman working undercover and Parker as a hostage. As tensions rise, Gideon launches a hazardous one-man rescue.
