"Rise from the Ashes" by midnitemaraud_r TEDDY/CEDRIC
http://midnitemaraud-r.livejournal.com/123071.html This story kinda blows my mind a little (uh, I mean it blows my mind a lot). This is the most complex and fully realized time travel fic I've ever read. It's long, tightly plotted, sexy, satisfying, thrilling... AMAZING! I know this is a really rare pair, but regardless of how you feel about either characters, do yourself a favor and read this anyway. It's really astoundingly good.
