I've been looking out for the next chapter of this, and I was shocked to see it was the last one. This is a painful ending for me, but I can see as it would be a hard story to end well. I really liked this story, it's unpredictable, genuinely unique, and opened up my mind a lot on the John/Sam pairing, which I really hadn't thought was very viable before. I think this story will stay with me awhile, I've already reread the earlier parts several times.
