Read this over the course of a few days while waiting around. Certainly it feels like a strange fable. Instead of talking animals there are precocious prepubescent twin orphans who memorize the Bible and who cut one another to harden themselves against pain, insult one another to harden themselves emotionally. I loved the scarcity of language throughout, the boys' commitment to narrating only things as they happen.
“We cut our thighs, our arms, our chests with a knife and pour alcohol on our wounds.”
There is just "the town" and "the war". The fact that Kristof was writing in her second language is interesting and maybe it was through necessity that she had the brothers speak so plainly. There is no embellishment, it is just this happened or that happened. As I understand it Kristof considered herself to be essentially mute and illiterate when she first arrived to Switzerland and was forced to learn French painstakingly while a number of her friends and fellow Hungarian refugees committed suicide.

Not sure if you're a gamer, but Le Grand Cahier was the main literary inspiration for Mother 3, which I think is one of the best RPGs of all time. The more adult stuff is not there obviously, but it has a bright, childish setting with a disturbing, unsettling tone at times, which I assume is also inherited from the book.
