I’m a Relaunch novelverse fan myself so I understand where you’re coming from.
I grieve the end of the novelverse, especially when I feel it often outshone the serialized writing that the new live action Trek shows have been struggling with. (I do note that some of the shows have been incorporating parallel plot and character evolutions and events to both the novelverse and STO.)
All of the new books, with the exception of the ones continuing to build on Vanguard/Seeker suffer from the requirement that the writers must “put all the toys back where they found them.” That is, they have to slide within canon and, by form, not have any lasting impact on the characters or universe. I think that’s why Mack’s latest Vanguard-related offering ‘Harm’s Way’ was considered by many to be the best new novel of last year.
That said, with Mack, McCormack, Swallow, and Miller writing the Picard-related books, they’ve all been better than I had ever expected them to be. Working off the bible for the show, they have dove deeper and often made what came on screen much more coherent.
