Star Trek: TOS McCoy/Spock post apocalyptic fic-Mute Spock

[deancas91190dc.livejournal.com]

Hi all,
I'm looking for a story I read a while ago on ff.net, set in ST: TOS universe, where Earth has been devestated somehow, cut off from the Federation, and Jim is dead and McCoy is leading a mute Spock around in a series of tunnels. They make a communicator or something and in the end Sarek rescues them. Anyone?
Thanks : )

Could it be "Things That Never Happened: Blue" by nemo the everbeing?
