I don't know if her observations are on point for Nigeria, but they are on point for the United States - or at least for some of the kinds of people she is running into in the book. She also manages to demonstrate how people's lives can be determined by their options (perceived or real), what they will do to change those options, and how well that works in most cases. Mostly though, it is just a very human story with extremely flawed people. Actions are judged harshly sometimes, but people are not. I always appreciate that in literature...and life.
