What is the author's tone in the novel, Oh, William!?

Over the course of the novel, Lucy's narrative tone remains measured and matter-of-fact. She describes the narrative world, her relationships with others, and her experiences in the recent past and narrative present with unaffected clarity. The sentence structures she employs are straight forward and unadorned. However, Lucy's almost sterile rendering of her story, world, and identity illustrate her reluctance to express real emotion.
