Not flourishing? Judging not just an author but a culture on the basis of one book?

Andrić's Bridge is certainly a different matter:
Stochastic Bookmark: Disquiet on the Drina
even though I like Meša Selimović's best even more as does Complete-Review:
Death and the Dervish - Mesa Selimovic

Not to mention the best emigre author currently writing in English, Aleksandar Hemon.
