Above, my pristine copy of Goblet of Fire that I bought a few years ago.
Below, my original copy of Goblet of Fire that I waited in line for when I was 9 years old and stayed up all night reading. And read countless times since then in all sorts of different situations and locations until it ended up looking like this. (We all know how long the wait between GOF and OOTP was!)
It’s my favorite Harry Potter book I own.
