"In grammar school they taught me that a frog turning into a prince was a fairy tale. In the university they taught me that a frog turning into a prince was a fact!" -Ron Carlson
Been browsing through Lord of the Rings fanfic, and I've actually found some good stuff. Just have to remember to stay away from fanfic.net. Thought I'd recommend one of the best, IMHO. It will especially appeal to anyone fond of those of the equine persuasion.
Promises to Keep - The Third Marshal of the Riddermark and the Ranger who would be King meet for the first time on the plains of Rohan. Told from a slightly different viewpoint. (Rated G, bookverse)
The site that story is archived on is home to many more excellent LOTR fanfics, if that's your thing.
