I went into this book not expecting much as 1) I'm not a reader of YA fiction and 2) it's yet another Holocaust story.
I was pleasantly surprised. I think that this may be labeled YA because the prose is straightforward and exceptionally easy to read; other than that, I don't see why it would be.
The story is, yes, another one in which the Holocaust plays a pivotal role, but what makes it stand out is that it doesn't get too preachy about it. It focuses more on the stories of individuals, and the brutality with which humans tend to treat each other.
Some people are annoyed by the narrator - Death - and the way it tends to interrupt the story. I liked the style, and liked how death was portrayed as an entity with some feelings toward those souls that he carried away.
