I found this fun website called tvtropes. Tropes are devices and conventions that consists of words used in ways other than what is considered its literal form. Metaphors, and similes are the most common. Tvtropes has analyzed some of the rhetorical devices used in The Reluctant Fundamentalist. For example, Ambiguous Situation -- why is Changez talking to the American in the cafe? Why is the American listening? Why does author use this device? Or how about the Evil Foreigner? After 9/11 Changez is seen as an evil foreigner especially with the "Beard of Sorrow."
I'm an expert amateur or maybe an amateur expert.
