Never has "Challenging" rung more true to me  - but in a diffrent sense than usual. There is a big chunk towards the end where i frequently had to take breaks because the describtions of what the characters exeprience is so horrific. 
However i did really enjoy this book even though it was darker than anything i had read in a while. I especially enjoyed the character of Frigg since  he reminded me of people i've met in real life - even though he is absloutly horrible. He was laugable throughout the book to a point where i laughed out loud because of his self interest and stupid observations. 

Anyway i don't get why this belongs in young adult it is pretty horrific to read and I wouldn't let anyone under 18 read it because of some of the graphic describtions. That said the book is very necessary especially because this is properly pretty close to the horrific acts of violence commited throughout the war.
