It does offer its own insights into such Romulan supporting characters as Donatra, Suran, and Praetor Hiren, but its interpretation of them is different from the novelverse's.![]()
Would you mind refreshing my memory? It's been a very long while since I read the novelization, and I don't have access to the book at the moment. (Weren't Donatra and Suran lovers?)
I remember reading Nemesis just after it came out and then having no problem with the continuity when "Death In Winter" came out, followed by all the other books. (I think Michael Jan Friedman might've even written an exit for the Madden character, such as talking to people in a corridor at a turbo lift, and then having the door open because it the system was being programmed and Madden turned and-well there was the end of Madden.)
According to Memory Beta the only mention in the novels of Madden was Q & A which features an alternate universe where Madden is indeed the Enterprise's first officer.
And, if memory serves, Picard's internal voice comments in Q & A that he'd never heard of a Commander Martin Madden anywhere in Starfleet. (Sorta a shame in a way, there could've been an interesting side-story there.)
Actually, isn't it sorta unusual for the novels to ignore the deleted scenes of a Star Trek film? All that's coming to mind right now is the line about Saavik's heritage from TWoK, but I feel like the rule of thumb for "expanded universe" material in Trekdom is to include deleted material unless it blatantly contradicts canon...?
