Okay, I'm half asleep and haven't read it in depth, but I think you're doing fine with it so far. I think the not-naming thing can work really well if you're going for a particular angle with it. Is there a deeper significance to the technique or are you just generally experimenting with not naming the character?
In any case, it reads fine without a name being attached.
Also, have you read "Contest" by Matthew Reilly? The theme of this fic reminds me a lot of that book, though I haven't actually read it, just been told about it. Was it inspiration?
