Theme – Out of their comfort zone

Black like me by John Howard Griffin. How a white American travelled thru the segregated Deep South of the 1950’s disguised as a black man.

Brave New World by Aldous Huxley when Lenina Crowne and Bernard Marx (two artificially conceived humans) visit the Savage Reservation and meet humans who still conceive naturally? They are both initially utterly revolted and literally miss their comfortable, clean lifestyle.

Delirium by Lauren Oliver with two societies living side by side (one within the city and one outside in the wild).

Trash by Andy Mulligan when Raphael, Gardo and Rat go into the prison.
