Summary: A Federation scout ship out in BFE discovers what appears to be an old Federation mining ship crashed on some desolate planet. When they hail it, however, there is a flash of white light and the scout ship mysteriously vanishes...
The Enterprise is off on some bullshit mission--trying with futility to create the metaphasic radiation effect from TNG: Insurrection in the inert rings of some random planet--when Starfleet phones them up and tells them to go check out what happened to the missing scout ship. They zoom over but don't find jack squat; before long though, the emergency transceiver Data gave to Geordi starts going off and Picard says "fuck this, let's go help Data!" and off they go to Orion.
Data sent the signal because he's been thrown in the Orion slammer. He was working with an agent from Starfleet Intelligence, trying to find out where Emil Vaslovik ventured off to with Data's mother; however, shortly after meeting with Data, the agent turns up dead. At around the same time, the Orion bank was hacked--and the only evidence left behind were some funky signals, unique to Soong-type androids.
When the Enterprise gets to Orion, Picard gets in deep shit. It turns out President Bacco is on the planet, having a secret meeting with the Gorn to try and get them to leave the Typhon Pact and come back to the Federation; the last thing Bacco wanted was for the Enterprise to show up and draw unwanted attention to the planet! The whole thing is a mummer's farce, however, because the Gorn are only there to distract the Federation while the Breen enact a massive covert operation.
Geordi and Smrhova do some investigating, and find--thanks to an annonymous tip--that the director of the bank himself was behind the security breech. They confront him, get into a firefight, and end up shooting off his hand--revealing that he's an android replicant. They go on a massive chase, and eventually catch him when Geordi phasers the floor out of a glass elevator, causing Kinshal to plummet quite a few stories. This whole business (along with some camera footage showing Data at a shop across town at the time of the bank attack/SI murder) grants Data a get out of jail free card, and he joins the Enterprise in their investigations.
At around the same time, during a dinner banquet, the president's advisor, Esperanza Piniero, tries to assassinate both the president and the Gorn leader--she fails, but takes down a few members of each race before she's stopped. (Picard is in the marital doghouse hereafter because he decided to save Beverly in the crossfire instead of the president--pissing the good doctor off, since Picard once chewed Jack Crusher's ass out for choosing family over duty back on the Stargazer.)
They take Piniero's android corpse back to the Enterprise and find that it doesn't actually have a functioning android brain; instead, it has an amalgamation of Romulan, Breen, and Tholian thoughtwave technology inside (onyx glass-looking stuff) that the Breen use to control the androids telepathetically--but the android had some sort of self-destruct that basically melted all the technology in the head. Piniero's (human) body is found in an Orion crackhouse, thanks to another anonymous tip.
2 more Breen-controlled androids attack the Orion bank, and successfully infiltrate the vault where President Bacco and Gorn Imperator Sozzerozs are hiding, killing all the guards along the way. Data intercepts the androids just as they're about to kill the dignitaries, but he notices that the second replicant had more than enough time to kill the president before Data could've stopped it... Curious.
The android Data killed didn't self-destruct, and the Enterprise uses it to track the thoughtwave signal to a planet...within Federation space! There they find the Breen operators freshly dead, still plugged into their controller machines. They easily hack the Breen computers and find the locations of androids ready to be activated on planets all over Federation space. Starfleet quickly scrambles the fleet to reach all the 'droid locations before they can be activated...
...But the Enterprise crew realizes that they found all of this information entirely too easily, and that the diversion of the fleet has opened up a corridor through space leading straight from the planet where the scout ship disappeared (at the beginning of the book) to Breen space. The Enterprise quickly intercepts, and sure enough, there's some kind of strange ship, capable of creating wormholes to a parallel dimension, being excavated from the planet. A Breen warship de-cloaks nearby, claiming they merely happened to intercept a distress call and are simply there to help. Picard tells him to back the fuck off or he'll nuke the crashed ship from space. The Breen say "there could be Federation personnel down there, you wouldn't date"--but Picard does dare, and launches a volley of photon torpedoes at the ship, utterly destroying it--and all the Breen's best laid plans. The warship limps back to Breen space, tail between its legs.
The Breen Domo is removed from office in disgrace; he gave up the Breen's best military secrets (i.e. the androids) to get the parallel dimension ship, all for naught. The Gorn--realizing that the Breen were willing to sacrifice them (making it look like the Federation did it) in order to start a war in which the Breen would end up controlling everything--are understandably pissed and start backdoor negotiations with the Federation.
Data bids a fond farewell to his friends aboard the Enterprise and heads off to find his mom and Vaslovik. He traces them to a distant planet, but once there his mom tells him that Vaslovik was abducted by the Fellowship of Artifical Intelligence.
Review: 4.5 stars. I really liked "Silent Weapons"; it had the political intrigue of Game of Thrones, with the gritty neo-noir atmosphere--and replicants--of Blade Runner. This is a great examply of how the sheer diversity of tales that can be spun in the Star Trek universe are what make it so great--and long-lasting!
This book had a lot of good character moments in it; I particularly appreciated that Geordi got lots of stuff to do, since he's usually just there to do the [TECH] stuff (it was pretty badass when he shot the floor out of that elevator). It also fleshed out Smrhova a bit, so she's starting to feel like a real character and not just another red shirt. We also got to further see how Picard is starting to care more about his wife and kid than his duty to Startfleet, so when the time comes for him to step down, it will actually feel believable. I didn't particularly buy it that Beverly was so pissed off at Picard for saving her life instead of the president's, but I guess she's more dedicated to Starfleet than I thought. I was definitely on Team Picard for that one.
I was really impressed by how much Mack fleshed out the Gorn; I quickly went from "oh great, the rubber-suited dinosaurs", to "wow, I actually want to read more books about Gorn society!" They did feel a bit overmuch like the Klingons--with all the focus on honor and eating raw meat--but they were distinct enough to feel like their own species. I also didn't really know anything about the Breen either (other than that they look like Leia in her Boushh mask), and Mack did a great job of making them slimy and covert, like the Romulans, but, again, different enough that they can stand on their own. Using thoughtwaves to power the androids instead of building a positronic brain was a stroke of genius, and feels totally plausible--it's just like VNCing into a computer than can walk and talk!
I've seen other reviews complain that this book seemingly has nothing to do with book I ("The Persistence of Memory"), but that's not really true. Without book I, Data wouldn't be back, of course, but this also ties up the Breen android plot that started in that book, and reveals what their big scheme was. I do agree though, that in the over-arching storyline of the trilogy, this book could probably be summed up as: "Data tracks down Vaslovik only to find he's been abducted by the android Superfriends."
Still, this is a great book (much better than the first one) and I'm eager to read part III!
