I usually try to google the author and the story title and go from there (or even just author nick and fandom). If there author is good there's usually rec list and stuff even outside of wherever the author may have posted (or other searches+). Did know about this particular author though and was sad to learn she left fanfiction... but thats life.

In general I recommend that you save the stories you want to reread (or everything an author has posted)... and I mean as a physical file and not as a link. Sometimes pages shut down without warning (like geocities did), authors move their stories to somewhere else, or remove some stories (or loose them for that matter) or make changes or even choose to leave fandom altogether.. the only true way to ensure you have the stories you'd love to read again is to do so.

Have a nice day:)
