The Book Thief
Rudy and Liesel
Although we don't know the details of Liesel's romantic feelings toward Rudy, which seem to be developing only as the story closes, there is still a romance going on. Since Rudy dies when he's fourteen, we don't get to know how this romance might have turned out.
Max and Liesel?
Obviously, there's a big age difference here – ten or eleven years. Still, some readers find their relationship romantic. Some wonder if they get married after their reunion in 1945. What do you think?
