Why does Liesel take the Gravedigger’s Guide and how does this tie in with our narrator?

The Grave Digger's Handbook is the first book Liesel steals and the first book she reads. As with all her books, this one is bittersweet. It's bitter due to the fact that she steals the book from the snowy graveyard where her little brother Werner has just been buried. It's her only tangible memory of her brother, and also of her mother. This ties in with the narrator, Death, because he is closely linked with death and graves.
