What is the author's style in Grace Notes by Bernard MacLaverty?

Even though an omniscient narrator tells the story, it is told completely from Catherine's point of view. Because the novel deals with Catherine's depression and grief, the reader is privy to all of her thoughts. Her thoughts flow rhythmically from past to present with small bursts of insight in between. Catherine views the world as being full of music. She finds sounds and rhythms in everyday things and creates music from combining these things with the lessons of her childhood.
