Synopsis: It began with a call for help - In the early part of the 21st century, the United Stated renewed it commitment to the space program, building a base on the far side of the moon. The first four missions of the new century went off without a hitch. But on the fifth mission disaster struck. First came an urgent message from Farside Base, then a total loss of communications. The launch of the FS-6 team was moved up to mount a rescue mission to Farside. But when they reached the base, they found a situation beyond human comprehension. The station was a mess, with graffiti scrawled everywhere, including the mysterious phrase, "food for the moon". Two members of the FS-5 team were dead, obviously murdered. A third died of fright soon after they found her. And the mission commander and two other astronauts were missing. Suddenly the FS-6 team found themselves becoming de facto detectives in a murder investigation for which there were no easy answers. And hanging over them was the threat that whatever had claimed the sanity and lives of their friends and colleagues might at any moment strike at them!
