I toyed with the idea of killing Gabe off completely, especially during the early parts of the draft. Early on, it was supposed to be about how suicide affected those left behind. That's why I initially made Gabe so dependent upon Auggie and Kyra. Then I realized, as I mapped out the entire backstory of Henry, that I really didn't want to write it that way. So I promoted Declan to a bigger part and decided to, instead, let Jude's death serve as a tribute to my original plan. So, no, the story did not go how I originally planned it to go at all. When I finally decided for certain that I was not going to kill off Gabe, by that point I was already around chapter six, I the drew up a rough idea of the set-backs which he would face, namely Henry's questionable issue with the subject of suicide. Most of those ideas ended up becoming part of the story. So I always planned to put Gabe through hell, but I didn't always plan for him to survive.
For the most part, I construct stories around a particular scene. For this story it was the opening scene. For Ground Rules, however, it was the umbrella scene in chapter eighteen, which was pretty much the beginning of that chapter. Borrowing Family was the same: it was contructed around chapter nine in the scene between Wes and Lachlan. There are exceptions to this, though. The Paradox Series was created from a general idea of bullying. The stories on which I am currently writing all stemmed from general ideas of various issues.
