Bernardo Atxaga
While Atxaga is definitely a novelist, Obabakoak
(The title Obabakoak
This is a brilliant, moving book. It does not exploit the reader. It is about storytelling. It is about storytelling in a language understood by a small group of people: a people that understand that if they were to choose not to use Basque, they would be complicit in the death of one of humanity's oldest and most distinct forms of speech. There is not a political word in the book; it is all political. When a writer chooses to write in a language that is marginalized, it is a political act. There are no literary signposts for such a writer.
