Angela's graduate school day at MIT comes to an abrupt end when she uses her hacking skills on another student's computer. Yet her mentor, Eve Abajian, arranges a new beginning for Angela -- as an intern in the FBI's Boston field office. Her new supervisor, Assistant Special Agent in Charge William Keats -- one of only two agents in the Northeast to make this rank before the age of thirty -- sees in Angela a fellow prodigy. But Angela's skills come with a natural curiosity, which is also a dangerous liability. With little training, Angela is quickly plunged into a tough case: tracking murderous brothers -- the Poet and the Engineer. When Keats tells Angela to watch and listen, her mind kicks into overdrive. The obsessive thinking that earned her A's on campus may prove fatal in the field.
