Brink of Disaster — Dave Elliott

Good doctors resist “jumping to conclusions,” but Dr. Rob Garcia does so often, and with panache. He commands a team of Army surgeons that parachutes into disaster sites, wrenching the critically injured from death's grasp.
Yet his wealth of medical experience cannot prepare Rob for what he next encounters �" a sophisticated terrorist cell of medical professionals hell-bent on destroying the nation's capital. He stumbles upon their plan to surgically implant time bombs in unwitting patients, intended to detonate simultaneously within seven Washington landmarks.
As the deadline nears, Rob realizes a greater fear -- his wife and daughter are at the Smithsonian.
