Erik Axl Sund took Europe by storm with his book Crow girl.
Have a look at his page

Not yet published in English, I think, but already translated to 30 languages. In UK the rights were bought by Harvill Secker.
The book was recommended to me by a [quite badly shaken-up]
friend who read a translation published here in my country.
I will be back with the news as soon as the book is published in English. I am not sure I will dare to read the book and I have read some pretty disturbing stuff without a problem.
(the only book in recent memory I abandoned because it was way too disturbing (AND ugly AND very badly written (IMHO, of course)) was The Road by Cormac McCarthy)
