I have not read Zadie Smith's latest book, NW, but it is on the top of my to purchase list.
Digital or print version, you ask?
I haven't decided yet.
I want a print version, but I would want a paperback and that's not out until June 6, 2013. I could get a digital copy, but then I won't have the pleasure of looking at it on my bookshelves.
Anyway, this is an older Zadie Smith interview (from September 2012) from Goodreads, which has many more excellent and exclusive interviews with writers.
