What is the author's tone in Let Me Hear Your Voice: A Family's Triumph Over Autism by Catherine Maurice?

The tone of the novel ranges between a variety of extremes as the author pours her thoughts, experiences, and feelings into the novel. At times, Catherine can be extremely partisan, in that she is clearly a strong advocate for behavioral therapy for autistic children. Having tried a variety of methods herself, Catherine uses her bias to argue support for this method, and for her rejection of other methods of treatment. On the other hand, Catherine's absolute rejection of other methods is at times tempered with objectivity, in that she herself admits several times to recognizing that for some children, behavioral therapy may not be the best option.
