Is the alien really what we think of, a Martian in an H.G. Wells's style? Or does it come in other forms as well? If the alien is genuinely alien and strange, will we be able to know it? Communicate with it? How? If we ever do, what relation will we have with it? Love? Hate? Aggression? Indifference? Ignorance? Exploitation? Misunderstanding? In this book, the different types of the alien found in Ursula K. Le Guin's science fiction are discussed. Her major fiction of the Hainish Cycle has been analyzed to explore her concept of the alien. It is an alternate history and future in which different types of humanity who live on nearby stars communicate with each other for the first time after an enormous period of non-communication. They have one source, however and it is not Terran (earthly)!Peaceful Hain is the source of the varied humanities encountered in this alternate universe and strange experiments in genetic engineering caused the anomalies encountered in this universe.This gives the author the right contexts to explore the physical, sexual,and intellectual alien and realize that the alien is actually a long forgotten or repressed part of the self.
