The Hit by David Baldacci (2013)

I am now trying to follow the Will Robie stories by Baldacci. As usual, he does not disappoint. Robie is an assassin for the government and his latest assignment is to get Jessica Reel, a fellow assassin that has started killing other members of their agency. The two of them are at an equal skill level, and though they have been pitted against each other, they end up saving each other's lives. As Robie pursues her, he finds there may be more to the story than he has been told, and that they have a common, larger enemy.
