Humanity has colonized the solar system, but crime still doesn't pay. David Carter is one of the most decorated agents in the Interplanetary Police Forces, but for the last two years, he's turned reckless, throwing himself into his work—or into the path of a criminal's bolt pistol. As a specialist in deception analysis and interrogation, Veronique de Tournay has been right where she wants to be: a profiler in the major cases bureau, Division 7.
Unfortunately, the director has reassigned her to Special Agent Carter, and neither of them are happy about it. After they stop a devastating attack on Mars, meant to kill thousands and cripple interplanetary travel, Carter and de Tournay discover evidence of other subversive attacks in the system. With time running out, the reluctant partners may be the only ones standing in the way of a conspiracy that stretches all the way from Luna to the Saturn Space Station.
