Overall, looks like a very promising and appealing story. Just afew things that I feel need to be looked at and possibly reconsidered: If this book is to be set in the time period that it appears, (that is, several years after the NJO) then the symbol wouldn't be new anymore. If it has been changed in the intervening years, I feel that that would be worth mentioning. Now, I'm pretty sure that this is some kind of practice system that they're using where the strobes indicate a simulated kill, and I feel that if that is the case that it should be better explained. I have never seen a system like that in any SW novels I have read (though I've by no means read them all). If it is a new system you invented for the book, then you should explain it alittle better.
