Seeking an older Nightwing x Raven w/Batfam Work of Fanfiction

I know this is a longshot given the track record of fanworks-seeking posts in the history of posts in this subreddit... but why not?

A looooooooong time ago, I read a story where Grayson is over in Seattle or Portland (I think) on business and encounters Roth in a business that she owned or managed. They talk over coffee, as one does in fanfiction, and she agrees to travel back to Gotham for a visit, staying at Stately Wayne Manor.

I recall she meets the Batfam in whatever line-up was in that particular story and winds up getting involved in some sort of investigation, taking up her Raven persona once more and adventuring across Gotham and perhaps into Bludhaven.

A lot of other details escape my memory, with the exception that I found it an interesting character study without any over-the-top sensationalistic trope-festing.

With the scant details I can recall, searching on AO3 and FFN (and other sites, frankly) is challenging, seeing that text-within-work keyword searches aren't available. I can't recall under which source/media it was filed: Young Justice, Teen Titans variant, Justice League, Batman variant, Nightwing... or whatever. It's one of the stories I regret not downloading, but I read it many moons before I began religiously downloading works of fanfiction.

Anyway, on the off chance that these few story elements spark a memory in someone, please respond with any further clues you might add to its title and/or hosting website.
