Alright, so I just listened to this - finished about ten minutes ago - and WOW, that was really cool! I enjoyed the story, it was engaging all along.
I only have one problem with it, but it's a philosophical disagreement with the Captain, not with the author. I mean, seriously... Suicide is a coward's way out, but inflicting that syndrome whose name I can't spell on yourself isn't? That is, to my mind, basically just as much a form of suicide. Refusing to confront the problem and retreating from it utterly. In fact, it's almost worse than suicide, in this case, since he is himself an extremely powerful weapon and I would bet that the nature of his real problem probably won't be forgotten any time soon by Kelly or anyone with whom she's shared it. It's only so long until this IMMORTAL SUPERHUMAN who is the most powerful creature on Earth is tapped as a force for evil through the manipulation of his self-inflicted syndrome!
...Alright, so I'm tired and rambling, but that was my only real peeve with the story. Other than that, I really liked it a lot!
PS: I don't dislike the Captain's decision in context. I think it fits with the character as he's established. I just disagree with the character's opinion and choice, lol.
