I've been avoiding her books but being a Polish I tried to appreciate her writings when she got the Nobel. I found her style technically very good, but nothing special (compared to other Polish literary giants like Miłosz, Szulz or Lem). The bigger issue for me was the contents - it was over-intellectualized and lacking in meaning; a classical triumph of form over content.

The best Polish female writer I've read is Maria Dąbrowska and her amazing book "Nights and Days". Something like Polish "The Forsyte Saga".
