You can use this thread to have a full on spoiler discussion of The Good that Men Do, Kobyashu Maru, The Romulan War: Beneath the Raptor's Wings and any subsequent books.
I'm just going to say that The Romulan War book left me on the edge of my seat, despite me finding the separation of the now very much together TNT a bit contrived. I recognize that Martin has to stick within canon, so Trip can't officially come out from the cold, dammit.
My guesses:
Sodok, Trip's Vulcan cover identity, will become T'Pol's husband of historical record, since they are very much mated at the end of the story.
I have a theory that Denak and Sopek might be the same person, and since T'Pol had very little contact with Sopek in Shadows of P'Jem this could be a possibility.
