Books Hannah's Read Where the Narrator Dies (MAJOR SPOILERS)

Whether the character is narrating from heaven, is undead, or dies at the end of the book it's always an unusual occurence. While main characters die all the time, I'm talking about the narrator, not just main characters, so books like "The Fault in Our Stars" does not qualify, I'm also excluding true stories like Anne Frank's diary or "This Star Won't Go Out," because the books were published posthumously and didn't actually die in the book. Major spoilers, complete at your own risk, you have been warned.
