Hard to rate a non-fiction book, especially such as this one. Can't rate facts, can rate writing. And well, it's a good one ! Managed to clear out a very complicated situation, that is the killing, for his unknowing reader, that is me. Well done, for the work of analyse and expertise itself, as well !
Although the unchronological order of the book can make it hard to follow at times. And I know it's not a fiction, but it still, at times, felt a bit too... facty ? not enough literary ? Hard to explain.
All in all, a nice book, which satisfied my curiosity about Columbine and what happened there, but that required an effort of me to reach the end.
