Cute story, and I was enthralled by the characters. I do have some reservations about the A.R.M.A. though. It's a good plot device, and I see how it can propel the story, but it does seem distinctly unscientific, and yet extremely advanced at the same time. It's hard for me to believe that Iliff, a student, would have bene capable of creating some sort of advanced human-machine interfacing AI, it with all it can do. It does seem like the story is slightly cognizant of this, though.
I'm thinking of the bit about the unexplained energy. To detect something, you would have to have a detector made in the first place, and know what to look for. I don't think it makes sense to have a general detector that can detect anything and everything. The MC does make a note along those lines.
Maybe you have plans for this.
In any case, that's just my opinion, and I could still enjoy the story in spite of this.
I wish you all the best going forward!
