Traces of India; east meets west
The author Salman Rushdie, originally from India, is perhaps most famous for his Satanic Verses (1989) and for the following fatwa against him in 1989; the book was seen as blasphemic by muslim leaders in Iran. Rushdie now lives in Britain, and so far he has not been injured (but some of his publishers and translators have!). He might serve as an example of how difficult it is to deal with religious and cultural differences, and of course the freedom of speech.
I have found an interview with Rushdie where he talks about this. Not everyone supports his ideas, though – I also found an essay dealing with some of the critique against Rushdie. Perhaps you will find some books by him at your nearest library?
There are of course lots of authors from India and other Asian countries now living in Britain or the US (see for example Monica Ali, born in Bangladesh, known for the novel Brick Lane).
