Survivor (Doubleday Science Fiction)

(Patternmaster #4) They fled from an Earth ravaged by plague and violence, seeking to fulfill their holy mission -- to discover a new home for humanity. But instead of landing in a peace-filled paradise, Earth's Missionaries find themselves caught between two warring civilizations -- the Garkohn and the Tehkohn. And only one of the people from Earth, a young girl and "converted" Missionary named Alanna, has the proper survival training to see through the lies of their Garkohn "hosts," who extend the hand of friendship to the humans only to enslave them.
