After Finland became independent, there was a rise of modernist writers, most famously the Finnish-speaking Mika Waltari and Swedish-speaking Edith Södergran. Frans Eemil Sillanpää was awarded the Nobel Prize in Literature in 1939. World War II prompted a return to more national interests in comparison to a more international line of thought, characterized by Väinö Linna with his ''The Unknown Soldier'' and ''Under the North'' Star trilogy. Besides Lönnrot's ''Kalevala'' and Waltari, the Swedish-speaking Tove Jansson, best known as the creator of ''The Moomins'', is the most translated Finnish writer; her books have been translated into more than 40 languages.  Popular modern writers include Arto Paasilinna, Veikko Huovinen, Antti Tuuri, Ilkka Remes, Kari Hotakainen, Sofi Oksanen, Tuomas Kyrö, and Jari Tervo, while the best novel is annually awarded the prestigious Finlandia Prize.
