Hello there!
Look Homeward, Angel: A Story of the Buried Life is a novel written by the american novelist Thomas Wolfe. The main character of the story is Eugene Gant, which it reflects the author depiction itself, and many themes are developed throughout the story, but the essential key fact of the novel was the human existence, portraying always the bounds of family ties, friendships and any other social web. And those complications of always trying to develop better and better all social bounds, lead the main character -Eugene- into the deepest place as well as his marriage with Eliza. His desires of living were ending as the time passed, their family relationship was decaying and taking every little stable aspect of his life into destruction and loneliness.
The author states a fictional plot with unreal elements to develop his story, and let the themes flow. This happened because the author develops the marital harmony theme -between Eugene and Eliza- through plot details, that is what the novel is mainly about, marriage and how this relationship makes an impact in a human-being life and existence.
