The setting in The Tree of Red Stars is almost a character in itself. The political turmoil of the 1960s and 1970s in Uruguay affects all the characters in the story. It is the setting of the story, as well as the consequences of that setting, that moved the author to write the story in the first place. Most of the characterization is used to put individual faces on the huge conflicts and the chaos that were taking place. Although the reader is pulled in by the stories of the characters' lives, it is the setting that makes this story unique.
