Not really. Everyone recommends the same 20 books that most have read or at least considered.

Let me give you an example that is real to me. I'd like to - 1. Read a fantasy series that pairs a human male and elf female romantically over the course of the series. - 2. What i'm looking for is to read the challenges of two fantasy races that aren't on very good terms so just being an elf won't really cut it. - 3. I also want a love interest that is a big active character in the story so not just a dozen mentions in a book. - 4. Obviously, i have to like the book(s).

It doesn't even have to be elves, it's just much harder trying to find such recs from a bespoke species.

You would think this would be an easy enough recommendation. Elves are the fantasy race after all and they usually aren't on the best of terms with humans. But it's not.. and at this point, i could give you more obscure recommendations that meet at least requirement 1, than you'd get in the vast majority of reddit threads. I spent months going through general amazon/goodreads recs and goodreads shelves with elves and still came out wanting.

Once you are even a little bit specific, options decay and if they exist, they are hard to find.

Shepherd looks good though

That type of deep analysis is hard, as nobody has access to inside the books (unless your are FB and do it illegally, plus have billions of compute dollars to spend) :)
