Sorry, Mark, I missed your October post on this thread. She is responsible for the hilarious LOTR diaries - "still not king" (Aragorn) "still the prettiest" (Legolas) - but made her name as Meg says in Harry Potter fandom, where she spells her name with an "i" I believe.
There was an article in issue 9.2 of Armadillo on fanfiction and Cassandra Clare in particular but I see that issue has not yet been archived - I'll try to fix it. There is a long review of City of Bones in the Current Issue (teenage) 9.3. You can find it on Armadillo Magazine Online
