Interesting concept, a guy in New York asking strangers on the subway what they're reading. Then he posts the results to this blog, Underground Reads. That sounds like it could be very mundane as well as very interesting.
The blogger, named Garth, is an English teacher at High School for Public Service in Brooklyn, and also a writer.
One of his posts involves the book pictured, and Garth gives this report:
Manhattan bound 2 Train, Winthrop to Grand Army Plaza Jackie felt caught with "trash." As soon as I asked her if we could discuss her book, she started laughing. She was reading The Undomestic Goddess, by Sophie Kinsella. "It's an escape," she called her experience of reading the book, which was recommended by a friend. "It's about a woman who quits her job as a lawyer a job as a house keeper, even though she can't cook and clean."
So, if you don't want to be caught with trash, don't read where this guy might be lurking!
