How likely is a thid DTI book?
With both TNG- and TOS-based books, maybe it's time (time
) to feature the next series, like DS9 or VOY?
Actually Watching the Clock
covered TNG, DS9, VGR, and ENT about equally. Lucsly & Dulmur are DS9 characters, after all, and the impact of Janeway's time travels was a significant element in the story.
At the moment, there are no plans for a third DTI book. To be honest, I'm still a little amazed I got to do even one of them, let alone two.
