The girl's death hits hardest, because it's a children's book that I read when I wasn't yet exposed to the concept of death in a mundane setting, and I really liked the character. It was a story of two imaginative and special friends playing in school, at their homes and in the woods near their homes. One of them couldn't get space to breath at home with their obnoxious and loud family, while the other had free-minded parents in a household without television and plenty of incentive to read and try artistic expression. The death is so realistic and unexpected. It's not an epic event where the evil villain strikes or there's a catastrophe, it's a simple accident and after that there's just a void, a lack of existence that can't be filled with words or else.
