I am currently beta-reading a fantastic fic by Alida-Fruit, called "Fading Hope." It's an excellent, epic "what-if" type of AU that is as monumental and moving as the actual Tolkien works. Here is the link if you are interested:

I have also beta-read a few vignettes by Alida-Fruit as well. The first is a lighthearted 'Hobbit' based fic featuring the Rivendell twins, Elladan and Elrohir. http://fanfiction.net/read.php?storyid=1345987 The second is the tale of an overlooked friendship; Legolas and Eowyn, and Legolas' last visit to his friend in her old age. http://fanfiction.net/read.php?storyid=1416208
