Deathfic, Kirk/McCoy Friendship

[fireworkwars.livejournal.com]

I'm looking for a Kirk deathfic I read a loooong time ago. So long ago, I can only remember bits and pieces:
-Pretty sure it was AOS
-Towards the beginning, Jim tells Bones that he's a great doctor
-The away team is caught in an explosion, and Jim is severely injured. McCoy freezes up while he's treating Jim, and Jim ends up dying.
-McCoy holds Jim's body in his arms and won't let anyone take him
-McCoy may or may not have started to hallucinate Jim (I could be mixing this part up with another story)

Hopefully someone knows the fic I'm describing!
