Before things get rolling over here...
If you’re looking for downloadable SPN fics, there are some places you can start with:
- Look at the PDF/Podfic section at Supernatural Story Finders to find links to collections:
- cherry916 maintains a wonderful PDF library but I can’t see any Destiel.
- The ebook library is realy awesome but sadly mostly dead I think. What a shame!
Of course there is always the incredible Archive of Our Own to rely on, where you can download fics in any format you please.
Flagfic gives you ebooks and PDFs of any fanfiction.net story and supports a couple of other archives, too.
