For the dedicated scientists who man a remote listening post on one of Saturn's moons, 2088 has been a pretty quiet year. After nearly 130 years of fruitless listening to the silence of the void, the men and women who represent mankind at the edge of the solar system are humanity's best hope for first contact. None of the specialists on duty could have ever predicted what is racing toward them-or what it means for humanity's future. Jarrod McKinley and two others are stationed on a listening post orbiting the moon Titan, part of man's latest effort to make contact with extraterrestrial intelligence. What the Titan base crew is about to experience will shake the foundations of the belief that mankind is alone in the universe. Without warning, a massive energy wave sweeps around Saturn and blasts the post. McKinley and his crew survive the initial blast, but the listening post is severely damaged. As a rescue mission is launched, a strange signal is discovered within the energy wave. Just as things seem under control, an explosion rocks the station; one of the crew is killed, but McKinley and Liza Alvarez jettison in an escape pod. McKinley senses some evil has targeted him and the newly discovered signal. As McKinley and Alvarez escape several attempts on their lives and race from Saturn to Earth, they survive repeated attempts to silence them, and they discover a plot that shakes the search for first contact.
