Cassandra Claire

Cassandra Claire is a difficult subject when it comes to fanfiction.

One one hand, she was responsible for The Very Secret Diaries, but on the other hand, she was responsible for the Draco Trilogy and wank. Lots of wank. And much of current Draco Malfoy fanon.

She's also had her very own urban fantasy series actually published, which is in and of itself much contention and up for debate as to whether it deserved to be published.
