About Andy . . .
A few people were interested in a more elaborate presentation on where Andy Fisher came from. While I'm working on that, here are the (relatively) recent blog entries relating to him and his inspirational origins (in chronological order; you can read them any way you want):
Andy Fisher appeared in two books before The Helios Conspiracy: Threat Level Black and Cyclops One. (He's also basically the character in another early book, but that's another story.) You can get Threat here; Cyclops here or here.
More on Helios on my web site.
