Vixen — Bud Sparhawk

When the Covenant entered the Thetti star system after a two hundred-year frozen voyage, her crew awakened to find a new world ripe for colonization. Meridian was everything they could have hoped fora ripe, virgin world more than capable of supporting Terrestrial life. Tam, the leader of the mission, suspects something is amiss when he glimpses a strange light over the planet...and a previously charted moon disappears. Sloppy work? Space anomalies? Or something new and sinister?
