So...okay...let's just state this right up front: As a story, this was relatively okay, and somewhat fitting in the TNG era, what with the ultimate resolution, etc. However, oh my science, I have so many issues with this. So, let me get the good things out of the way first - after the content warning, of course.
So, big, big content warning: Riker, who apparently attended Starfleet Academy between the ages of 15 and 19, in his first year, meets a woman, who he then sleeps with right away, and later falls in love with (whilst still being 15, mind you). We are never told this woman's age, but when she chooses to end their relationship, when Riker is 19, she tells him that she has her own son who is four years old than Riker. So, when he was 15, she had a 19-year old son. So, at best, she is in her 30s, at worst, she's older. Why do we need a pederast in a Star Trek novel? Why can't Riker just have attended the Academy at a normal age, like 18 to 22 or so, like everyone else seems to. Sure, Wesley seems to test at 16...but, he's already got a leg-up, being an "Acting Ensign," serving on a ship-of-the-line, and is a "genius." Riker can barely tie his shoes together on a good day...I also don't think bang-every-female-alien Riker spent his whole time at the Academy in an serious, long-term, "I'm gonna marry this woman," relationship. I'm not saying a middle-aged woman preying on an 18-year old farm boy from Alaska is much better, but at least it's legal...in most places.
I love, love, love the expansion of Dr./Lt. Selar's character. I always wanted to know more about her ever since her appearance in "The Schizoid Man." She just seemed like this calm, cool, and collected Vulcan with a bit of a snarky side - probably one of the most relatable Vulcans portrayed - maybe it was the actress channeling her inner K'ehleyr. The idea of the "make you go crazy, kill everyone" art museum touring the galaxy is also fun. And Data was just his best self in this novel - when Data is Data, my heart melts a little. :)
Now...on to the bad. Okay, let's talk about this cover. On the right, we have a little Andorian girl. Her name is Thala, she's a child who was residing on the Enterprise with her father, who was killed when the Borg attacked them in the J7 System. Since then, she's been sort of living on the Enterprise, under the care of Dr. Selar, who's been trying to find a new home for her. Now, Thala is blind, like Geordi, so ignore the fact that she clearly has eyes on the cover. So, when the crew encounters the "make you go crazy by looking at it museum" you would think that this blind, little girl (with a child-like mind more open to wonder and possibilities) would be the key to overcoming this dilemma...but nope! She's matters fuck all to the overall story, except for giving Dr. Selar something else to do. I spent the whole novel thinking she was a sort of Chekov's Gun...and she was literally nothing. She was a do-nothing, go-nowhere B-plot. Maybe cute, maybe fun, maybe feel good...but overall, meh. The A-plot was resolved 20 pages before the end, and we spent those last 20 pages on "The Adventures of Selar and Thala"...
Secondly, the Kill-Museum was described as absolutely indescribable, made up of shapes and colors, angles and lights, designs and forms, completely incapable of being processed by the humanoid brain (think the Medusas from TOS - almost). Just to look at it unaided can drive one insane - which is a Trope that I will never understand. I will never understand how there can be a shape that I can't process, or a color previously unknown - that's not how light works, nor how my retinas process it. But, if you were the artist who was told to depict that would you go with a shiny, crystal rock? Because that's what we got.
Also, Data is sorely lacking here. This is a Data story. He resolves the main plot. He's undertaken writing a novel (historical romance - "historical" as in it takes place in the early 22nd-century...probably) and shares it with a few people, we even get to read the same excerpt from it a few times as he accepts feedback and rewrites it. I guess I really shouldn't be upset about cover art...but Star Trek covers are deliberate advertisements, showcasing characters and ships or locations.
Minor nitpicks: There's a Tellarite doctor, who is alternatively referred to as a doctor and a nurse in different scenes - by the same character. She becomes a hero, of course, but still, get the damn title straight. Also, Tellarites have hooves? And, again....and, again...and, again...there's so much talk about money. Dr. Selar talks about needing to save up to pay for Thala's passage on a freighter. LaForge talks about spending two years worth of his pay on something. Things are talked about as lacking because of the need for funding here and funding there...it's so aggravating. How can I have my glorious, gay, space-communism, if I have to keep reading about their money issues. It really takes me right out of the universe...as well as being wrong in context. Oh, and of course, boy-genius Wesley's "passing thoughts and ramblings" provides the necessary epiphany Data needs to resolve the main plot.
Oh, and Andorians have women who are pretty much forced to live lives in breeding harems where they pretty much lose all their agency? And Andorians are one of the founding races of the Federation? Am I missing something here? Did Andoria get to exempt themselves from signing the Federation Charter?
Should you read it....sure, why not...
