What is the author's style in The Inheritance of Loss by Kiran Desai?

The book is written in the third person omniscient . The narrator knows everything that all the characters are feeling and often switches from their thoughts and straight into dialog. Since the book takes place in two different settings, it was important for the narrator to know everything about the characters and portray the feelings and thoughts to the readers to give the necessary closeness and physical and emotional distance that they were feeling.
