Dubravka Ugrešić was recently announced as winner for this year. Here is the press release:
I've only read The Ministry of Pain, and I thought it was good, but nothing more than that. Didn't move me to look for more of her works. Does she has something that can be caller her masterpiece?
However, among the female oriented shortlist (http://neustadtprize.org/finalists-f.../#.Vi64636rSUk) she mas the more viable winner due to international presence. Guadalupe Nettel is a very good writer, but she is young her body if works is quite short yet.
