Wow, that was really well written! Normally I don't enjoy romance related fics that much, but you really write the emotion so well!
I like how you interpret details that make total sense, such as Kirsty settling for the safety of Miles, but never really giving up the dreams of the excitement with Kane. My favourite part of the entire fic though, was how you portrayed Kane. You always seem to portray him well, but in this fic you particularly succeeded in doing so. It just made a lot of sense to me that he'd end up like he did, not married again, but as a captain alone with the sea. That just made a lot of sense to me somehow, I don't know, it was just a great detail to the fic
