The series had its genesis in 2002 when John J. Ordover, then the Senior Editor for
Trek fiction at Pocket, had the idea of doing a twelve-book series that would chronicle the year leading up to
Nemesis. The idea would be to set up the various events of the film: why Worf was back in Starfleet when we last saw him as an ambassador, what led to Riker and Troi deciding to marry, what led to Riker finally getting his own command, why Crusher decided to go back to Starfleet Medical, what Wesley was doing back in Starfleet, and why Data seemed to have lost his emotion chip.
We started with a brainstorming session that involved John, freelance editor Carol Greenburg, me, Bob Greenberger, and John Vornholt at a Chinese restaurant in Brooklyn. We covered a lot of the major points we wanted to deal with. John wanted to cover Wesley, Bob wanted Riker and Troi (it was at that dinner that we decided to have the particular traumatic event that occurred in Bob's duology), and I wanted Worf's return to Starfleet, which also meant I'd be closing the series out, since the script at the time had Worf saying he just returned to Starfleet from his diplomatic post.
As time went on, some changes were made, in part because Wesley's role was reduced to a no-line cameo in the film, so we decided
not to set the reset button and left him as a Traveler. Both Worf's line about being a diplomat and all the references to Crusher going to Starfleet Medical were removed, but we stuck with those, as Crusher's through-line in agonizing over the decision whether or not to take the job was something we all wanted to tackle.
"Collaborate" may be a strong word. Mostly we just kept each other posted as to what we wanted to do. I also kept a master crew roster so that we could have characters appear in subsequent books -- e.g., Dr. Tropp, the Denobulan deputy chief medical officer, created by Dayton and Kevin and used by the rest of us to some degree or other; Taurik as the deputy chief engineer; and the various members of Vale's security detail.
Somewhere in there, it was decided to cut it down to nine books and make my finale a single volume.
Other things: Bob set Dave's duology up by having Koll Azernal be behind the events of his two books, and he also set up my finale by mentioning the inspection tours. Dayton & Kevin and Dave both made use of Worf in such a way that set the stage for his journey in my finale.
My favorite: Bob had a security guard named Carmona, who was defending Picard throughout
Love/Hate, and who survived despite spending a goodly amount of time in those two books being shot at. Dave then blew him up while he was relaxing and having lunch.
We also checked with each other on various things relating to Crusher and Data, in particular, since their plots went through most of the miniseries.
Hope that explains things.
