I'm sad to see that you haven't updated this for so long :-(
Indeed, I find the idea really original and I would like to read more
(and I had guessed that Harry and Zhaan would at least try to be together... I would bet that a certain father just caught them ...)
Author's response
Yes, I'm sorry I still haven't finished this. I kind of stalled out in the fight scene at the end of the story and there just wasn't enough interest out there to inspire me to work past it. I have another fic in progress that is taking me two years between chapter updates, just because I seem to have lost my urge to write.
Just in case I never do finish (though I do still hope to) you are correct that John caught Harry and Zhaan, but just kissing. Neither Zhaan nor Aeryn really let him get away with pulling the protective father routine, though.
