Servare Vitas.

To save lives. For the men of the FBI's elite Hostage Rescue Team, it's not just a motto; it's a creed they live by. Nobody knows that better than Special Agent Nate "Doc" Schroder, the team medic. As a former Pararescueman, Nate is accustomed to going into harm's way to save people—including his wife, Taya—no matter the risk to his own life. But when a catastrophic event turns the tables on the team, suddenly he's the one whose life needs saving.

However, survival is merely the start of Nate's battle, because it's going to take a lot more than medical expertise to pull him through the dark days ahead. While his teammates rally around him, Taya fights to drag the man she loves back into the land of the living. With her at his side and his team at his back, Nate must find new reason to dig deep as he struggles to become whole again.
