The first time I've read LOTR it took me about a month - would you expect anything better of a 9-year-old? When I reread it the summer before last, it took me 1 week. I've just reread it recently again, but I have a lot of homework and other commitements, so it took me 3 weeks. It's probably not the work that slowed me down, though, but savouring every word (like others said before me
).
