Finally got to this one, and I liked it. The whole bit of "The
Enterprise mediates peace talks between warring factions and someone is trying to sabotage them" setup could have been routine, but the involvement of Lenore Karidian and the baggage of her past with Kirk and Riley gave it a lot of emotional weight and tension, particularly with the characters' doubts -- especially Lenore's own -- about whether she was truly sane and reformed. Unlike some, I liked the hostage rescue sequence, which felt very much like the kind of thing you'd see in a Trek movie from this era.
And I disagree with those who've said that Kirk shouldn't have brought Lenore to the ship because of her reputation.
Star Trek is supposed to be about a future where people don't discriminate or give in to prejudice. And the assumption that a criminal can never reform or that a mentally ill person can never be healed is just one more prejudice. Lenore was rehabilitated and paid her debt, and she deserved to be treated the same as anyone else, not hated for the rest of her life for something she did as a result of an illness that's now been cured. I admired Kirk for his commitment to basic fairness despite his personal baggage.
One problem I did have with the plot was that it could've been easily resolved if they just had security cameras in the corridors. But it's been long since established that, for some reason, Starfleet vessels do not have such a thing, and thus Greg was just being consistent with the universe.
Still, I wonder why a tricorder scan of the murder scenes didn't pick up the evidence detected by Chekov's respiratory system.
The alarms that sound when an unauthorized phaser is fired seem to function some times and not in others - and their existence is even deliberately pointed out.
I noticed that, but the later instances happened after the ship had been damaged, so maybe the sensors were down.
Kirk bringing Lenore onboard without telling Riley just plain isn't believable. I couldn't believe he would do something so stupid.
It was mentioned that Kirk did try to give Riley a heads-up, but Riley was in meetings all day and couldn't be reached.
The plot hinges on a transporter 'trick' that's featured in a TOS episode that's apparently been unclassified and become common knowledge. If this was so easily reproducible it'd be a problem on a galactic scale.
Except the book also establishes how dangerous it is, and how desperate one would have to be in order to try it. The attempts that were made to compensate for the drawbacks of the process proved unsuccessful. Nor was it easy, since the safeguards on the transporter had to be disabled.
One, my reading of the book seemed to indicate that Chekov was new to the job of security chief and was proving himself up to the task for the first time to Kirk. That not only flies in the face of what we see in TMP, where Chekov is established as Security Chief there in 2273, and with the fact that by 2288, the time of the book, Chekov had not just been Kirk's security chief before, but the first officer of the Reliant for some time as well.
I didn't get any sense from the book that Chekov was new to the security post. Indeed, I seem to recall references to Chekov's past experience in the post. However, the time frame of the book would place it not long after TFF, and thus probably less than a year after Chekov
resumed his old post as the
Enterprise security chief after several years serving as
Reliant's first officer. That could account for any sense that he has something to prove.
And since it's 20 years after "Conscience," that would put it in 2286-7, depending on your TOS chronology. The Okudas put TFF in '87, so this would have to be after that, though I've never been able to justify putting it later than '86.
