Are the Shatnerverse novels completely out of continuity with the main novel range, or are they sort of able to be squished into one continuity?
The first couple of trilogies seemed as though they could fit if you squinted a little, but the third trilogy overtly contradicted the rest of the novelverse in multiple respects, including the timing of Bajor's admission to the Federation and the events of the first year of Titan
's mission. And both Ex Machina
and Cold Equations: The Body Electric
contradict what The Return
alleged about V'Ger's origins and relation to the Borg.
I really enjoyed that anniversary trilogy of TOS Gateway stories, whose name I forget, and I know they really didn't fit into the main continuity.
That was Crucible
. I think you mean the Guardian of Forever, since Gateways
was an unrelated miniseries.
