Will Robie, who was introduced in Baldacci's novel The Innocent, is one of the U.S. Government's top sniper/assassins. When a fellow assassin suddenly begins killing fellow agency members Robie is given the task of hunting her down and killing her. Rogue agent Jessica Reel is a professional who equals Robie in skill and talent so the hunt is a real challenge. Soon it appears that there is more to the killings than just an agent turned enemy. Robie has to figure out if Reel is really committing treason or if there is another reason for her targeting the agency higher ups and others in the federal government. Soon Robie is not sure who to trust. The twists and turns in the story make it a page turner (although I was listening to the audiobook). Robie is a likable character in spite of being a trained killer. This book can be read without having read The Innocent, but the ending leaves open the possibility of the series continuing. And while I enjoyed the audio version, the addition of sound effects was occasionally problematic when listening while driving. On more than one occasion I was looking in my mirrors at the sound of approaching sirens before realizing they were part of the story.
