There are many aliens who live among us in science fiction stories such as the Men in Black, but Timothy Zahn has a unique and original way of taking a tribe plot and turning it into a fantastic storyline. This is an action oriented story where it is almost impossible to figure out the characters motives and nobody knows who is a friend or an enemy. This makes for a lot of suspense and the onus is on the reader to figure out who is friend or foe. There's a surprise twist at the end of the story that makes THE GREEN AND THE GRAY a very exciting work of speculative fiction.
