When a mystery is central to the plot of a novel - when the plot develops because of the mystery - and then the mystery is shrugged away with barely a murmur at the end, left unsolved - one must suspect that there IS no solution, that the author had no idea who was behind the critical sabotage: that he himself, not any character, is the culprit. I was very much aware of "author intrusion" off and on as I read this book, beginning with the needless rehashing of the series episode "Amok Time" (surely every Star Trek fan *knows* that story, and readers who don't won't care!). But nowhere was I more aware of the author than at the end: I closed the book and said out loud, "What a cheat!" Weinstein never demonstrates that anyone *could* have sabotaged the Federation installation; not only that, but by having the unknown saboteur's programming escape the intense scrutiny of Spock and Scott *even after they knew that sabotage had occurred*, he demeans these characters' skills. The only true reason for the sabotage is (besides creating some tension) to provide a reason for one lone Empyrean's change of heart, and to achieve this single end, Weinstein is (I'm sure unintentionally) disrespectful to Star Trek characters and to the reader's intelligence. This is a contrived novel and one I found very disappointing: I still want to know whodunit and WHY, and I don't believe the author knows.
