In 2009, Müller enjoyed the greatest international success of her career. Her novel Atemschaukel (published in English The Hunger Angel) was nominated for the Deutscher Buchpreis (German Book Prize) and won the Franz Werfel Human Rights Award. In this book, Müller describes the journey of a young man to a gulag in the Soviet Union, the fate of many Germans in Transylvania after World War II. It was inspired by the experience of poet Oskar Pastior, whose memories she had made notes of, and also by what happened to her own mother.
In October 2009, the Swedish Academy announced its decision to award that year's Nobel Prize in Literature to Müller "who, with the concentration of poetry and the frankness of prose, depicts the landscape of the dispossessed." The academy compared Müller's style and her use of German as a minority language with Franz Kafka and pointed out the influence of Kafka on Müller. The award coincided with the 20th anniversary of the fall of communism. Michael Krüger, head of Müller's publishing house, said: "By giving the award to Herta Müller, who grew up in a German-speaking minority in Romania, the committee has recognized an author who refuses to let the inhumane side of life under communism be forgotten"
