What is the tone in the tortilla curtain?

Answer 1

Boyle uses a very sarcastic tone to make a satire out of the novel. He uses these sarcasm comments only when he writes about delaney and kyra because of his contempt for americans. all in all he says that the americans are self centred selfish crazy etc. usually boyle writes more witty and funny -ironic but not in this case. he thinks that the book is too serious to make a fun out of it. and the sarcastic tone i mentioned: He doesn't uses it when he talks about america and candido

Answer 2

The Tortilla Curtain is a metaphor for the border between Mexico and the U.S.
