“The Draco Trilogy” – Cassandra Claire
This is a fanfiction based on Harry Potter. It’s also more than 2,500 pages long. Seriously. It’s considered one of the most legitimate Harry Potter fanworks out there and has been reproduced in print and in downloadable PDF form online. It’s super entertaining and very inventive, sticking faithfully with JK Rowling’s writing style. It’s no longer available online but, um…I have it on a flash drive.
