Liesel is a book snatcher. When she stole The Grave Digger’s Handbook, it was totally fine. No one was going to come back for it. When she steals the hot book from the book burning, that was okay too. No one was going to read it. It was going to sit there and burn. When she tried to steal the book from her teacher, that wasn’t okay. Someone was going to read it eventually. If something is lost, forgotten or obstructed, no one wants it. Or they would have taken better care of it. Just take it.
