I like when Kathy is telling her personal narrative. She does not make either religion, Christianity or Islam, out to be better. Rather she describes her choice of religion to be based purely on her experience of the religions, instead of philosophical reasons why one is better than the other. She changes to Islam because it gave her clarity when she needed it. I don't think that the author is trying to convince you one way or the other weather you should be Islamic or not, instead the author is just showing how the family experienced living their religion. This makes the characters much easier to relate to, and enjoyable to read about.
