I am only about a third of the way through NORMA by Sofi Oksanen, but I know without a doubt that I will be reading all of her books.
Her bio from her homepage reads -
Finnish-Estonian novelist and playwright Sofi Oksanen (b. 1977) debuted in 2003 with Stalin’s Cows, which won her the recognition of Northern Europe’s readers and critics. Her international breakthrough came not long thereafter with the publication of Purge. Translated into more than 50 languages, the novel earned Oksanen the title of “literary phenomenon” in American press and innumerable awards, there-among The 2010 Nordic Council Literature Prize. Sofi Oksanen has with her powerfully evocative narrative established herself as the greatest voice of her generation. Her latest novel Norma, published in 2015, introduces yet another aspect of Oksanen’s authorship. It is a bold entry into new landscape where reality’s darker sides are edged with a whisper of old magic.
Sofi Oksanen is the recipient of many prestigious awards including The Finlandia Award 2008, The Mika Waltari Award 2008, Cristina of the Year 2008, The Great Finnish Book Club Prize 2008, The Runeberg Award 2009, The Nordic Council Literature Prize 2010. Prix Femina Ètranger 2010, Europe Book Prize 2010, Swedish Academy Nordic Prize 2013, Budapest Grand Prize 2013 and Salerno Libro d'Europa Prize 2015.
I have been scouring the net for an interview with her talking about Norma, but have yet to find one.
Here is an interview with her from 2012, old but still gives a little insight into what makes her tick. - https://saltmin.com/2012/05/06/interview-with-sofi-oksanen-an-internationally-well-known-finnish-writer/
