What is the author's style in Uglies by Scott Westerfeld?

Despite being a sci-fi novel, this book does not include a great deal of strange language that was made up in the author's mind in order to describe the indescribable. The author has used simple terms to refer to the surgically altered people of this society as well as the locations and cities that populate the novel. For this reason, the language of the novel is not difficult to understand and is quite friendly to the intended audience, young adults.
