A series of deadly explosions rock the city of New York and with too many victims and no known motive, the F.B.I. turns once again to Dr. Lucas Page.

On a beautiful October evening, New York City's iconic Guggenheim Museum is closed for a tech company's private gala. Until an explosion rocks the night, instantly killing 702 people, including every single attendee?yet the damage to the building itself was minimal.

An explosion of that precision was no accident and, in response, the FBI mobilizes its entire team -- but the sheer number of victims strains their resources. Were all 702 victims in the wrong place at the wrong time, or was there only one target and 701 unlucky bystanders? That many victim files is a staggering amount of data to sort through and Brett Kehoe, Special Agent in Charge of Manhattan, decides that he can't do this without more computational power.

Dr. Lucas Page, astrophysicist, university professor, and former FBI agent, is uniquely gifted for the task at hand. He can visualize a crime scene as if he was a bystander and can break down any set of data at a glance. Even though Page wants nothing to do with the FBI, with his city under attack and his family at risk, he steps in to find a killer in a haystack before they strike again.
