I found a Silmarillion fanfic by accident that it infinitely brilliant -- an apocalyptic thriller about Elves in modern times! It pitches the two most Doomed families of Tolkien's canon against each other -- at least so far, perhaps they learn to cooperate eventually. Amrod and Túrin managed at least one sensible conversation already, at this point.

Summary:
A drilling rig off the coast of Norway breaks down under mysterious circumstances. A petroleum engineer in North Dakota gets called off a major discovery because there's trouble back at home. It's the Dagor Dagorath, as apocalyptic fiction set in modern Earth starring the reborn Children of Húrin, and anything else I say would be a pretty major spoiler.
( My additional blurb for this is slightly spoilerish the way blurb for for-pay books usually is )
