When a fire started seven years ago, Mia Briscoe and her best friend Serena were attending a frat party. With the exception of Serena, everyone was present. She vanished from sight, leaving no trace. Even though Mia is now an investigative journalist covering New York City politics, she isn't giving up on learning what really happened to her friend that evening. Mia discovers she knows just where to look when she comes across hints in an old picture from the fraternity party. In order to piece together a dark sequence of events that all started with that catastrophic party, she enlists the aid of FBI agent Sherlock. However, there are strong and deadly individuals who will stop at nothing to keep the past hidden.

Olivia Hildebrandt, a CIA agent, is leading a team in Iran with the goal of infiltrating an undercover agent who has been betrayed. A teammate saves her after an exploding grenade almost kills her. Not only has that team member vanished after leaving Walter Reed Hospital, but two men also show up at her residence with the intention of killing her. Savich thinks the compromised mission in Iran is what led directly to their attack on Olivia. What kind of intelligence was this about? Who turned on them? Savich soon discovers that invisible adversaries will do anything, even murder, to make him a target.
