The daughter of a U.S. Senator is monitoring her social media presence when she finds a picture of herself on a strange blog. And there are other pictures...of the children of other influential Washington politicians, walking or standing outside their schools, each identified by name. Surrounding the photos are texts of vicious political rants from a motley variety of radical groups. It's obviously alarming--is there an unstable extremist tracking the loved ones of powerful politicians with deadly intent? But when the FBI is called in, there isn't much the feds can do. The anonymous photographer can't be pinned down to one location or IP address, and more importantly, at least to the paper-processing bureaucrats, no crime has actually been committed. With nowhere else to turn, influential Senators decide to call in someone who can operate outside the FBI's constraints: Lucas Davenport.
