What is the style of writing used in The ones who walk away from Omelas and how does the author uses this style to make their point

The Ones Who Walk Away from Omelas is narrated in the third-person by an omniscient (all knowing) narrator. The author's narrative style is eloquent but simple. Her descriptions of the city capture its beauty and grace. Le Guin uses simple language to create pictures that clearly illustrate the horrific circumstances of the child. Her in-depth descriptions are easy to visualize, enabling the reader to develop a very clear mental picture of Omelas from the beginning.
