She wrote the Broken Bow novelization in two weeks, in those conditions?
One of the novelizations she wrote in four days. I want to say it was "Endgame."
Looking at the bibliography again, the Star Trek: Challenger
series that Carey initiated as a successor to New Earth
even died aborning, not having gotten past two entries in the Gateways
And there were certainly plans on her part to continue the series. She had discussed them at the time, and they were a unique approach for a Star Trek
Starfleet assigned another ship to patrol the Belle Terre sector, and that ship carried orders for Nick Keller to return to Earth for reassignment. Keller instead resigns from Starfleet to operate as a privateer in the sector using the Challenger
(which he could do, since it was the planet's ship, not Starfleet's ship). The tension in the series would have come from the conflict between Keller and Starfleet.
Thinking in terms of Carey's interests and politics, Keller and his ship would have been the equivalent of the colonial/early Republic militia, while the Starfleet ship would have been the equivalent of the US Army fort overseen by a representative of the far distant government back in Washington.
Of course, none of those plans ever came to fruition.
