Clouds Over Snowby Murasaki99
A Snape-centric story, featuring no one that I recognize from the Rings trilogy, but it's been a while. Snape is very much Alan Rickman, playing off of an original female character with very little trace of the Mary Sue about her. The necessary Tolkein backstory is filled in with digestable chunks of exposition and useful footnotes, and the plot itself (a Nazgul in the Potter-verse) is very cool. Not finished yet, but still good stuff, and s/he seems to be updating fairly frequently.
