For you Ranger fans like me, I found this little gem tucked away amidst all the girl-falls-to-Middle-earth stuff at ff.net. Good characterizations and a spooky plot, as befits a Spooky Arda LJ community post:
Guarding the Heedless FolkWritten for the 2008 "Six Days of Spooky Challenge" at the Spooky Arda LiveJournal Community. When a man disappears, the Breefolk reluctantly enlist the aid of an untried ranger. Characters: OC, Halbarad, Aragorn. PG for violence.
There's not many reviews for it at ff.net but maybe she received plenty wherever else it might be posted. Regardless, it deserves some good reviews.
