Hi Marzi.So, The answer to this question depends on some more information. Do you want something about British English culture or the cultures of other English speaking countries? Do you want a novel, a fictional story? Or do you want a book that gives facts about culture? If you want information about American culture, I recommend The New Dictionary of Cultural Literacy.

There are so many out there. Here's a link to some: https://www.quora.com/What-are-some-recommended-books-about-the-British-culture
