Summary: In the past: Noonien Soong, Ira Graves (TNG: The Schizoid Man), and Emil Vaslovik (Flint from TOS: Requiem for Methuselah) travel to the ice planet of Exo III (TOS: What Are Little Girls Made Of?). There, they discover a chamber; inside, an android with a phaser hole blown through its midsection. They stick him into a shitty, spinning, duplicating machine, but this also happens to wake up hundreds of other bigger, meaner androids on the planet. Soong, Graves, and Vaslovik escape, but only just.
Presently: Data has just returned to the Enterprise with his recently deceased android "mother", Juliana Tainer (TNG: Inheritance), in tow; he inters her alongside Lal and Lore in his chambers. Since Worf is on Deep Space 9, the Enterprise has a brand new security chief, Rhea McAdams--who is small and likeable, but tough and capable. She and Data have a meet cute, and before long, Data shows her that he's fully functional.
An incident occurs that calls the Enterprise to the Daystrom Institute on Galor IV. Admiral Haftel (TNG: The Offspring) explains that Bruce Maddox (TNG: Measure of a Man), Reginald Barclay, and Emil Vaslovik were working on a new android with a "holotronic" brain, but shortly after they activated it there was an accident, caused by severe "weather." Vaslovik is presumed disintegrated by an electric discharge (or something), Maddox is in a "coma", and a portion of the roof caved in and destroyed the android. However, "DATA" was written in blood on the ground near Maddox, and foul play is suspected.
After performing an "autopsy" on the android, they realize it was a (near-perfect) fake, and suspect Vaslovik may have taken the real android and disappeared. While searching his house, an away team made up of Data, Rhea, Riker, and Barclay are transported to Vaslovik's secret lab, hidden away deep beneath the ocean. They find unknown art by da Vinci, music by Brahms, and any android every mentioned in a Star Trek episode--and Data realizes Vaslovik is Flint. Shortly thereafter, the away team is ambushed by giant, angry androids (like Ruk) and are forced to flee in the base's escape pods.
In space, the Enterprise is losing a battle with a giant iceberg-like ship, piloted by more Exo III androids. Riker and Barclay basically do a kamikaze run with their escape pod, but are teleported out at the last minute by Sam, the Ten-Forward bartender--who also turns out to not only be an android, but the original Exo III android who created the 'droids who are attacking them presently; he escaped Exo III by stowing away on the Soong-Graves-Vaslovik ship when they fled.
Data is badly damaged in the attack, and Rhea tries to save Data by interfacing with him--turns out she's an android too, the holotronic 'droid that went missing from the DIT. She can't save Data alone, however, so she takes him to Vaslovik's secret space station. Data is saved, but before long the base falls under attack--the ice ships tracked the pod, but so did the Enterprise. Data and Rhea get beamed aboard one of the ice ships; Flint gets beamed aboard Enterprise. It turns out that the ancient androids are after Rhea--they want to put her in their spinny-copier machine so they can upload themselves into duplicates of her, hoping to "fix" their shitty, angry programming.
Data triggers M-5 back on Flint's base, a super-powerful computer that will do anything to survive (TOS: The Ultimate Computer). While M-5 fucks up the ice ships with volleys of torpedoes and phasers, Data and Rhea escape out into space via exit hatch and start fucking up the ice ship with their bare hands, like they're both the Incredible Hulk or something. They're ultimately saved though when Sam--feeling like a dick because this is all his fault--leaves the Enterprise in a shuttle and flies into the atmosphere of a nearby planet, with the ice ship following suit. The planet's silvery atmosphere is actually composed of Wesley's nanobots (TNG: Evolution), and they consume both ships--assimilating the androids into their collective in the process, where they all live happily ever after.
Back on the Enterprise, Flint has disappeared--and taken Data's mom with him. In the epilogue, he restores her back to life, and they too will presumably live happily ever after. Rhea breaks Data's heart by leaving him (and Starfleet) to join the Fellowship of Artificial Intelligence (Sam's club)--so Data's the only one who doesn't get a "happy ending."
Review: 3 stars. This book was OK, but there wasn't much to it; really, the story seemed to be entirely based on bridging the gap between TNG and as many androids from TOS as possible (luckily TOS is on Netflix so I was able to get caught up on the episodes I've never seen). It's really hard for me to imagine the TNG characters on the low-budget sound stages from TOS, using crappy technology from the 60s and pretending it's super advanced (I found it quite amusing when Soong and Graves were saying how it makes no sense that the android duplicator spins the way it does).
I'm also not interested in Flint/Vaslovik, who the book heavily revolves around. Particularly, I find it terribly lame that Brahms, da Vinci, et. al. are all supposedly the same immortal human--it's so eye-roll inducing. It would actually make more sense that he's an android himself, and that's why he has such an interest in robotics--I almost wonder if that will turn out to be the case in the Cold Equations trilogy.
Rhea McAdams was a fairly compelling love interest for Data, but then she leaves at the end and everything resets back to normal, in typical TNG fashion (I'm hoping she also shows up again in Cold Equations). I admit that I didn't see the twist coming that she was the missing android; I guess I wasn't reading closely enough, because it seemed like she had already been on the Enterprise for some time when the Daystrom incident went down--so instead of being shocked, I was more like "uhh, WTF?"
I thought the characterizations of the rest of the Enterprise crew were done well enough, but they certainly weren't featured much--and when they were, they were doing battle with a bunch of android ships that apparently looked like icebergs--another "WTF" for me. I did quite enjoy seeing Data's emotional side--over his mother's death, falling in love, etc.
So overall, not great, but not terrible either. It hinged too much on TOS backstory for me, and really didn't seem to be "about" anything and was just an excuse to bring Flint and a bunch of old androids into the 24th century. I only read this because Cold Equations is a direct sequel, and I probably won't read it again.
