I’ve read a lot of fanfictions in the three years since I’ve first discovered them and these are just a few of them, the ones I’ve read most recently. Most of them, if not all, are rated M with some T rating in some cases. I encourage you NOT to read them if you are underage as they contain adult themes, coarse language and/or sexual situations.
The list will be expanding as I continue to read and enjoy fanfiction works from different fandoms.

Without further ado here are my Non Harry Potter favourites:
Alice in Wonderland, 2010
CSI: New York
Gilmore Girls
Lie to Me
NCIS
Peter Pan
Pirates of the Caribbean
