Christopher, you've been pretty vocal about what was on the 'shopping list' of things you were given that needed to be included in GTTS, but was the death of Janeway mandated by TPTB and not PAD - and if so, how much of the rest of the novel was on the shopping list?
As
Defcon says, that was decided by Margaret, not the chimerical "TPTB." I want to emphatically reject the implication in your question that some committee at CBS/Paramount or something is dictating the content of Trek novels. It's all the editors and authors, mostly the authors.
The "shopping list" I've described for GTTS was very brief and general, and I've been "vocal" about it in order to make it clear just how minimal it was. I was asked to resolve the thread of the
Einstein, but wasn't told how or required to make it a central element of the story. I was asked to set up the state of Picard and Beverly's relationship as Dave defined it in the
Destiny outline, but it was left up to me whether that relationship would include marriage or not. I was asked to kill off one of two characters but given my choice as to which one. And I didn't have to include as much of a Borg focus as I did.
So if you're implying that Margaret Clark plotted BD and just gave it to PAD as a subcontractor to fill in the details, that's a gross misunderstanding of the jobs of editors and writers. There are no "shopping lists." The editors and authors are collaborators in the development of an ongoing novel continuity. Coming up with individual novel plots is the writers' job, but the editors are the "showrunners" who manage the development of the overall continuity. The things an editor asks for in a novel, therefore, are mainly just the points that are relevant to that larger continuity -- where certain characters or events need to end up by the conclusion of the novel, for instance. It's up to the authors to figure out how they get there and what else happens along the way. And a lot of what the authors come up with on their own can influence where the editors decide to take the metanarrative (as with
Vanguard, where the authors' choices in the first two books led to a major departure from the plan outlined in the original series bible).
