The plot hook thing has been mentioned. I didn't really think, as I was writing it, that it was necessary, but with some of the comments I've gotten, I'm beginning to think I was mistaken. I've resolved to work some of those up for other enhanced fiction pieces I do.
The piece I'm working on now (tentatively titled "Father to Son," though that's likely to change) is related to ARN only in that some of the characters from each story know each other, but it will have plot hooks by popular demand.

It's also probably going to be a little longer than ARN, which was kind of a test of the waters for me (and, really, for CGL too, I think). The follow-up for ARN will follow FTS; still working on some plot points for that one, though.
I can't make promises, but most of my stories are going to have dates on them. It helps me as a writer keep track of things.
The one place I would have disappointed you if I had done a Plot Hooks section would have been backgroun on "We." I know it would help GMs, but I think it would damage some of the mystery. As a writer, I really don't want you to know much more about "We" than Thomas does...which is just about squat. Their goals were pretty clearly spelled out by Teresa, and it's clearly bigger than just one person. Mr. Big (not his real name) has a plan and the wherewithal to do something about it. Beyond that, at this point, you could tie a lot of things to "We" and probably not be wrong.

I'm pleased you liked the story. I am, in fact, quite chuffed about the response it's been getting in general. Thank you very much for the kind words.
