Just from the previews I've seen, it's clear this book and the novel continuity are taking different approaches. (There's a page with Bryce Shumar commanding the Intrepid
during the Romulan War, when the books establish that he's already in command of the Essex
by that point.) And as I've said, I don't see the need to force them together. Star Trek
tie-ins over the decades have routinely offered multiple interpretations of offscreen events, and that makes them a richer experience than if you had to settle for just one version of how a given event might have unfolded.
