Plot summary
The protagonist, Lysander (Sandy) Washington, has been raised by aliens, the Hakh'hli. When their interstellar ship arrives at Earth, Sandy serves as part of the aliens' liaison team with Earth. Pohl uses Sandy's alien perspective to make some observations about our culture.

Sandy believes his alien friends are peaceful and benevolent, as they present themselves to be. However, after it becomes clear their plans are far from benevolent, Sandy has to decide whether to side with the aliens who raised him, who are the only family he knows, or to side with humanity. This decision becomes more complicated when he learns he is only partially human.
