Farside, the side of the moon that never faces Earth, is the ideal location for an astronomical observatory. It is also the setting for a tangled web of politics, personal ambition, love, jealousy, and murder. Telescopes on Earth have detected an Earth-sized planet circling a star some thirty light-years away. Farside observatory will have the largest optical telescope in the solar system as well as a vast array of radio antennas, the most sensitive radio telescope possible, insulated from the interference of Earth's radio chatter by a thousand kilometers of the moon's solid body. Building Farside is a complex, often dangerous task. Breakdowns--mechanical and emotional--are commonplace. Accidents happen, some of them fatal. But what they ultimately find will stun everyone, and the human race will never be the same.
