Best FF That Proves the Light at the End of the Tunnel Is the Light of an Oncoming Train: The Art of Losing, by penknife. X-Men movies, Magneto/Xavier. The title comes from Elizabeth Bishop's One Art, and the poem and the story nicely complement each other. You know, Magneto in the comic books and movies never did much for me, but I'm developing a tremendous appreciation for him via fan fiction. Yet another sign, I guess, that FF writers are better than anyone the canon's got these days.
Best FF That Proves That Sometimes Student Loans Can Be Touchingly Romantic: In Thicket, by Martha. The Sentinel, Jim/Blair. This story quotes my third-favorite Philip Larkin poem, This Be the Verse. As with most stories set after the canon's last episode, this one is angsty and emotional. I suspect a lot of post-last-episode FF writers were working out their anguish at the way their show ended. Entry #317 on the "Why We Can't Trust the Canon Authors with the Canon" list, I suppose.
Best FF That Leaves You Hoping for a Different Ending Than the One You Know Is Coming: The Chain Series, by guede_mazaka. James Bond (GoldenEye), James Bond/Alec Trevelyan. The link takes you to a page with links to all the stories; make sure you read them in order, I to VII. Each of these short slices of the lives of James and Alec was inspired by a different bit of Sylvia Plath's poetry. This set of stories is just one more proof that Alec Trevelyan was the most interesting Bond villain ever. It's also yet more supporting evidence that Sean Bean can bring the slash anywhere, anytime, in any costume whatsoever. The man has, I don't know, slash genes or something. Anyway, these stories are marvelous. Frankly, they're better than the movie they're based on.
Best FF for Insomniacs Who Need to Know It Could Always Be Worse: Civilised, by Sam Vimes, aka copperbadge. Harry Potter, gen. I know, I know. Gen. Again. What is this world coming to? But it's good, and better yet, it's Lupin-as-I-see-him. (I find most Potter fans have preferred versions of the characters; I'm not sure if this is indicative of a flaw or a strength in Rowling's writing.) This story could also work as an entry in Chicken Soup for the Fan Fiction Reader's Soul, except that naturally if there was such a thing we'd have to hunt down the compiler and force him to read every single story on fanfiction.net. That would show him where he could put his damn chicken soup. But, no, really, this story reminds us that we tend not to value what comes naturally. I know that sounds unbelievably dull. Look, just read it, OK?
