I have finished reading White Teeth: A Novel by Zadie Smith. It is a very good and fun novel. I would recommend it highly. It has very entertaining images of the different characters and their peculiarities. The English guy Archie and his Jamaican wife Clara, the Bengali Samad and his wife Alsana and their children Millat, Magid and Irie are all very interesting characters. The idiosyncracies of the immigrants in the story are very interesting and also generally true. However, it did seem to me that at a few points Zadie Smith confused Indian, Pakistani and Bengali culture, or may be I am mistaken. I am not sure.
The book describes some of the problems of immigrants and has a few characters, especially Millat, who get into militant Islamic organizations. The story rings true, but don’t read it to get an insight into Britain’s extremist Muslims. This is a novel, a work of fiction and not a sociological study.
