About the book: year / "Sister of the Earth" is a collection of the best works of the famous American writer Poul William Anderson (born 1926). A physicist by training, he wrote detective stories, historical stories, fantasy, but most of all succeeded in the genre of fantastic literature, as evidenced by the many Hugo and Nebula awards that he received. The works included in the collection tell about the contacts of earthlings with aliens, and vice versa. And in each of these creations the personality of the author himself emerges: a brilliant storyteller, endowed with remarkable imagination, a master of paradoxes, but, above all, a person who remembers that “we are always responsible for those we tame.”».
