I know these
secret diaries are old, but I wasn't interested in LOTR when it first came out. I just found about them from somebody (I can't remember who) in
Joi's IRC Channel. They're pretty good and funny, and it's a shame that Cassandra has stopped writing them. Make sure you read from right to left, i.e. Aragorn, then Legolas, then Boromir, etc. There's also 3 diaries from ROTK; my favorite is
Legolas' account. Others have tried to imitate Cassandra, but they aren't very good. Hopefully I can find some more funny LOTR fanfic.
