I just completed reading this novel. It's the last original series numbered novel I had left unread. Memory Alpha gives the year it takes place as 2267, which is probably about right. The time frame definitely appeared to be sometime during season 1. Chekov does not appear at all, Lt. Kevin Riley is still at navigation and Yeomans Rand and Tonya Barrow appears. References are made to season 1 episodes as well, such as "The Menagerie".
It's basically 2 stories connected together. It starts off with the Enterprise on a mission to help some planets restore their computer databases after a flawed update is sent out wiping out their databases (which seems a bit implausible to me since one would think the Federation would have back-up systems to prevent that--but the novel was written in 1997 so it's possible the writers had not considered that). Their job is to help the various planets restore their databases using their own back-ups if they have them or trying to reconstruct them from other sources. The colony on Tyrtaeus III is very independent minded, and many of their colonists would prefer total independence from the Federation. So the computer glitch does not reflect favorably on the Federation obviously. The crew is met with suspicion and almost open hostility. But they succeed in restoring their database.
Which leads us to the 2nd part of the story. An asteroid-like object is on course for the systems sun. The Enterprise finds what appears to be life on the asteroid and plan to investigate. Being that it is their system the colony leadership insists on having representatives on board to monitor what happens. Captain Kirk reluctantly agrees, since the Federation does not want to lose any members and Kirk doesn't want to be the cause of a rift by acting rashly. So one of the leaders who is more inclined to want to remain in the Federation and a more open minded assistant of hers go with them. Meanwhile her political rival has machinations of his own, but as she can't really prove he has ulterior motives she can't air her suspicions.
Eventually they find they can't divert the asteroid from its collision course with the sun and they are concerned based on some of their readings that it could have a detrimental effect on the sun. When they board it to investigate the crew, except for Spock, finds it hard to function inside the asteroid. The passageways are bizarre and the colors on the ship cause the other landing party members issues. They feel they are getting closer to the indeterminate life signs but eventually give up in the maze of bizarre corridors.
Eventually Spock boards the asteroid on his own via shuttlecraft and ends up trapped their when an energy field appears. Kirk is distressed because they cannot beam Spock out before the asteroid enters the sun. But then they are contacted by Spock and eventually he encounters the mysterious aliens on the ship, who have foregone their physical existence in favor of one that appears to be more thought and illusion. Comparisons are made to the Talosians, but Kirk and Spock soon learn that it is very different. However it has caused them to be insular and afraid of outsiders. Like the colony, they prefer to be left alone. Eventually it leaves the system unaffected and the colony appears to decide to remain within the Federation for now.
So overall, it was a decent enough story. We do have a truly alien species and other than some political intrigue on the colony, it's not your typical villain story. The aliens are not villains, it's really all just a misunderstanding basically. The colony is an interesting story in and of itself. Typically the Federation is treated as a utopia, even in the 23rd century. Why would anyone want to leave it or not be a part of it? So it presents a different dynamic. Though the story is ultimately presented as, well, 'why would anyone not want to be part of the Federation.' It doesn't really present the colonist view point in any sort of positive manner. Though they are self-sufficient and hard working so it's not totally negative. You might wonder why the Federation just doesn't say good riddance to such ungrateful ingrates. But then that's not how the Federation works. We are stronger together after all.
The aliens are true aliens, though they appear humanoid to Spock, Kirk and McCoy. Which I thought was a bit unfortunate. Earlier on the asteroid environment is portrayed as totally alien...to the point that it actually causes the human crew members discomfort and even a bit of nausea. It would have been more consistent had the aliens appeared as such (we are told their appearance is likely similar to their 'true' physical form).
The main flaw I saw was the 2 apparently distinct stories that really don't tie together. The earlier story about the data crash is basically the 'excuse' to make sure the Enterprise was in the right place at the right time and is basically discarded in the 2nd half of the book. There's nothing wrong with dual stories. I liked the recent A Contest of Principles which actually had 3 stories going on. But it's all the way it's handled and in this case there is no real purpose to the first story except to make sure they are there for the 2nd. A fair amount of the book was spent on that first part as well (I can excuse it more if it were just a chapter or 2). And the aliens were a bit disappointing after the build-up. You're expecting something totally alien by the time they finally communicate with Spock and it's sort of a let down.
So overall their was some potential for a great story here, but I think the book falls just short of that potential. I'd probably say it's an average book. It holds your interest but you find yourself wanting more.
