Ooh, I haven't read "Roadtrip" yet! (Blasphemy, I'm sure, with such a high recommendation from you.)

I can't help it -- I'm at work, reading XF fic, but I keep coming back to "Parabiosis". The prose is so beautiful and perfect and out of this world metaphysical, it makes me want to die a little, every time. Out of HAPPINESS. Because it is AWESOME. (As does everything else Penumbra wrote, but "Parabiosis" will always be her best.)

That said, I will definitely be reading "Roadtrip" today. Whee!
