The Book Thief

I think that it was very fitting to have the entire novel be narrated by death. Death in a way, is kind of the heart and soul of the novel because Death encounters more people and situations then any of the other characters. Death would have to be the most interesting character to me because usually people think that the only thing Death cares about is taking a soul, but he seems very interested in the story of Liesel. This could also be Death's conflict with himself. It knows it shouldn't become interested in the lives of people because it is more used to the death of people.
Death's perspective is definitely first-hand. It encounters more on people's lives than anyone else can. Its main priority is collecting souls, but it also witness's the heartache and sorrow which follows death, and sometimes the lonliness.  Death sees more the the gruesome side of the war, and sometimes is saddened by whose souls it takes. This could explain why it went against it's usual custom to see into the life of Liesel.
