I finished the book. It was ok, but not great. I did end up liking Sulu's story in the book, but Kirk wasn't done well, and Spock/McCoy and the other main cast members besides Kirk and Sulu were barely involved, and like I've seen mentioned the few Spock/McCoy interactions were very weak (as were most of the parts with people not named Sulu). I just realised that he was the author of Typhon Pact - Plagues of Night and Raise the dawn, which I really enjoyed. This book, however, was mostly average and I doubt I'll read it again.
