Summary: It's been 30 years since the breakaway fleet went through the Laconian gate. Paolo Cortazar is the president of Laconia University and the head of its exobiological studies. He has devoted his life to studying the protomolecule, and keeps people who have been deliberately infected with it in a high-security building called "the Pen." He uses the subjects to create protomolecule-modified human stem cells that he's been injecting into the High Consul, Winston Duarte, in an effort to make him immortal.
Drummer is the Transport Union President, currently on the transfer station at Lagrange-5. After 3 decades, Earth is finally beyond its environmental crisis and is ready to trade with the colonies. She attends a press conference with the Earth-Mars Coalition (EMC). Afterwards, she gets a report from Medina Station of an unauthorized transit out of Freehold to Auberon, which pushes the gates past their ship-swallowing safety curve, causing all sorts of delays. She commands Holden to go to Freehold and tell them that their repeated violations have resulted in a ban on all traffic in and out of their gate for 3 years.
Alex remarried to a woman named Giselle, with whom he had a son named Kit; he also got divorced again. Clarissa has to undergo constant treatments because her aftermarket glands are killing her; Amos always takes care of her. Bobbie is worried that their visit to the colony will be fatal; the colonists are well-armed, and the 3-year blockade will most probably kill everyone, since the soil isn't suitable for growing food yet.
Santiago Jilie Singh is a captain in the Laconian navy. He is summoned by High Consul Duarte for reporting the insubordination of his commanding officer. Duarte puts him in charge of The Gathering Storm and says it's time to show the rest of humanity what they've been working on.
Holden tells Payne Houston, the governor of Freehold, that he either comes with them to face trial, or the whole planet is cut off for 3 years. The Interim Governor Semple Marks brings Payne to the Rocinante, hog-tied.
Drummer is on People's Home, 1 of the 3 void cities. She intends to use Freehold's punishment as a warning to Auberon, who has a working polypeptide cross-generator that can modify any soil grow Earth crops--which would greatly shift the balance of power. She tells Holden his solution won't work, as the TU doesn't take prisoners. She sends him a statement to read.
Holden won't stand for Drummer's orders, as they amount to the mass murder of people who never voted for her. Naomi suggests maybe they should just retire to Titan instead of trying to save the universe again, and he is quick to agree. Suddenly, the ship changes course; Payne broke out of the brig and took over their systems.
Payne has locked himself in engineering, so Bobbie takes a space walk and comes in from the outside. Though Payne dents a fire extinguisher over her helmet, Bobbie makes quick work of him. Later, Holden offers to sell her the ship so he and Naomi can retire. She gets choked up and says she'll uphold the Roci's reputation.
Captain Singh of the Gathering Storm meets Admiral Anton Trejo of the Heart of the Tempest, Laconia's largest ship, with protomolecule-enhanced hull plating that regenerates. Trejo is a former Martian, and a military genius. They discuss their upcoming assault on Medina Station.
Holden and Naomi tell the crew they're retiring; everyone seemed to know it was coming (except Bobbie). Bobbie asks the crew if they'll stay aboard with her as the captain, and they all agree.
Drummer gets an alert from the Laconian navy saying they're opening their gate and heading to Medina station to address Laconia's role going forward. Everyone assumes the Laconia colony is failing and making a last ditch attempt to strong-arm their way back with a deprecated fleet. Drummer seems to recall that they had a protomolecule sample, but doesn't give it much thought.
At Medina, the Roci crew celebrates 1 last time. Afterwards, Bobbie returns to the captains quarters on the Roci, and finds a (mandatory) security meeting request about Laconia. The Tori Byron and Medina's railguns are to take the lead, with the Roci falling back to stop any boarding parties. When the massive sea-creature-esque Laconian ship comes through the gate, it disinegrates the Tori Byron with 1 shot of a strange, magnetic weapon.
The railguns on Medina rip holes into the Laconia ship, but the hull heals itself almost immediately. The Gathering Storm fires its magnetic weapon again, destroying all the railguns on the station and half the electronics in the nearby ships. Colonel Tanaka boards Medina with teams of marines in protomolecule-enhanced power armor, and they quickly take over the station. Admiral Trejo tells everyone that that things will continue just as they have, but expedited by the Laconian fleet, who now control all 1300 planets. The only price is cooperation with the new order and a small tax that will be invested into infrastructure and planetary economies. Opposition will result in immediate death.
Drummer meets with Chrisjen Avasarala. She has studied Duarte's thesis and knows that if he's attacking, he's sure he can win. Drummer will have to give up everything beyond that gate for now (including her husband Saba on Medina station) and focus on securing the Sol system with the help of Earth and Mars. Avasarala says she has some back channels into Medina.
Singh is the new governor of Medina. When he calls in the station's security officer to relieve him of duty, the officer says that when Singh fired the magnetic weapon, it built up a ton of energy and all the gates simultaneously discharged massive amounts of gamma radiation. Singh thinks this may help them gain control of all the systems without even firing a shot.
The Roci crew pieces together that Duarte gave the Free Navy Martian tech in exchange for early access to the probes sent through the gates, which is how he knew Laconia had something that could be used to make their new tech. Some Belters launch an attack with a few weapons that haven't been confiscated.
The Laconian marines easily dispatch the attackers, but Singh's assistant is killed. He orders security chief Tanaka to tighten the screws, and when she expresses resistance, fearing that it will cause the Belters rebel more, he relieves her of duty. He sends Trejo a briefing about the gamma burst from the rings caused by their USM field projector, suggesting that they move their invasion timetable up significantly.
After the crackdown imposes curfews and checkpoints and outlaws large group assembly, Holden and Naomi decide to get the Roci crew back together. They find that everyone's been turned off the docks and have no idea how to find the Roci crew with the messaging system locked down.
Amos sets up a meeting with the underground, where they meet the resistance head, Saba. He's not sure he can trust them until Holden strolls in like a celebrity. Bobbie silently resents being relegated to second in command again.
While Drummer reviews strategies, Carrie Fisk from the Association of Worlds puts out a statement saying they will cooperate with Laconia. Cameron Tur, a scientist, tells Drummer that after the Laconian ship/fired its weapon, there was an uptick in the activity of the nearby space: it was boiling.
The Eye of the Typhoon is dispatched from Laconia early to act as gate security, using the gamma ray burst discovery. Trejo will be taking his destroyer into the Sol system to fight the fleet on their own turf. He tells Singh that he fucked up firing Tanaka, and says he should talk to her; Singh tells her he knows he acted brashly, but her transfer still needs to go through or he'll look weak.
Bobbie tells Holden her plan of attack and insists that he pass it off as his own so Saba will accept it. The first step is to try and intercept the encrypted data the Laconians are transmitting; they can decrypt it later. Bobbie and Clarissa hijack some panels outside that station with relative ease and start collecting data.
The Heart of the Tempest comes through the Sol gate and politely demands cooperation. Drummer's void city, People's Home, is being outfitted into a war ship. She has the satellite used to communicate with Medina shut down so the Tempest doesn't notice the transmissions, and she immediately misses Saba. She puts out a statement saying the incursion will be repelled. Duarte only sent 1 ship and it will take weeks to reach them, but Avasarala says it's only hubris if he loses.
Tanaka's replacement, Lt. Overstreet, informs Singh that another Laconian life was lost in a terrorist bombing. Singh tells the 7 suspects that only the first to say who made the bomb lives. Then he meets with Carrie Fisk of the Association of Worlds and tells her that it's now the Laconian Congress of Worlds. He tells her to issue a statement to the dissenting worlds that if they don't get on board, their planets will be sterilized.
Saba intercepts a transmission saying a second ship just as large as the Tempest will be coming through the gate in 42 days, so they don't have much time left to act.
Saba sends Bobbie and Amos to meet with Katria of the Voltaire Collective, who keep setting off bombs that are not helping their cause. Amos starts a fight during negotiations, but he and Bobbie take down 5 of Katria's goons. They agree to join the collective, but Bobbie fears retribution.
The attack on the Tempest does not go well. It immediately repairs any damage, and has so many rail guns that it takes out most of the attackers easily, including the void city Independence (population 100,000). The Tempest does not fire on any fleeing ships. Avasarala comforts Drummer afterwards, explaining that now they know where the railgun and PDC embankments are so the next attack will fare better.
After Singh publicly plays a video of the battle, Holden realizes that they need to make a run for it, not try to join up with the others for an unwinnable fight.
They propose a plan to get the decryption keys to Katria: Naomi will copy the files, then they need to bomb some nearby oxygen tanks to cover up their operation, then they'll sneak out in vac suits. Katria agrees.
Singh tells Fisk to let the planets know that limited trade will be allowed again soon. Afterwards, Katria's bodyguard Jordao asks to meet Singh. He tells Singh he'll spill the beans about an upcoming attack if they let his sister out of prison.
Trejo sends Drummer a message saying she has 18 hours to submit, or he'll destroy Pallas-Tycho station. She orders the people on Pallas-Tycho to evacuate.
Just as everyone is in position for the operation, Alex sees on his drone feed that there are 2 guards in the decryption room, and 1 is near a dead man's switch that will trigger an alarm. Holden starts setting off all the alarms he can so that alarm will just be more noise amidst chaos. He gets caught by Martians in power armor.
Alex takes out the guards with his drones, then blows the door. Naomi copies the files from the server and they all retreat so Katria can set off her bomb. Amos wants to save Holden, but Bobbie says they can't jeopardize the mission. The explosion is huge, enough to damage The Gathering Storm, which is docked just a few meters away.
The Tempest shatters Pallas into dust with their magnetic weapon, but it also causes every person in the Sol system to hallucinate and lose a few minutes-worth of time. Scientists assume that this non-propagating event probably happened to the crew of the Tempest as well. Drummer wants to intercept their report that will be routed through Medina, so she wants to open connections back up to Saba.
The bombing on Medina killed more Laconians, so Singh orders marines to be stationed nearly everywhere, with all nonessential areas shut down. Singh tells Jordao that he wants a list of names of possible insurgents or his sister will be re-arrested and hung publicly. Afterwards, Singh gets a report from Trejo that a sphere of black light appeared on their ship when they used their magnetic attack, and he thinks it may be an inner weapon. Singh does a quick search and finds that Holden reported seeing the same ball of light on Ilus/New Terra--the same Holden they have in lockup.
Saba's techs decrypt the data and find the security documentation for the entire station--they're so detailed that they're worried they're fake. They show where prisoners are kept---so they hope to break out Holden--as well as the Laconian's entire plan of attack, and all their protocols, which closely match those of the MCRN and MMC. They also find a backdoor into the marine armor suits that can shut them down remotely.
Singh shows Holden a picture of the bright-black nothingness that appeared on the Tempest; Holden immediately recognizes it as the "bullet" that appeared on Ilus, the thing the "other" aliens used to turn off any protomolecule technology. Holden tells him to contact Elvi Okoye, the scientist from Ilus who spent years researching the artifacts there.
When Laconia was founded, Duarte recognized that the slow zone was a choke point that would cause endless wars and environmental collapses made worse by the lack of a central response. He chose Laconia because of the orbital construction platforms with which he could create his fleet. His ultimate goal is to bring a peace that will end all wars.
Bobbie finally tries to talk to Amos, but he immediately incites a fight. He lands a few decent blows, but mostly Bobbie beats him to a bloody pulp. Afterwards, he tells her that all he wants in life is for Peaches to be able to die peacefully back on the Roci. All he can think about in the meantime is hurting people, but he knows Babs is the only one that can actually beat him; no hard feelings.
Naomi comes up with a plan: they need 2 bombs, so Katria will make 1 and she says Jordao will make the second.
Holden is transported by the Lightbreaker to Laconia for interrogation. Jordao warns Singh that something big is going down, and it will involve the sensor arrays.
The Sol defense force engages the Tempest at Leuctra Point, successfully targeting its weak spots and doing definite damage to the ship--enough so that they manage to get a nuke through that detonates. They're quick to celebrate their victory, but when the fireball clears, the Tempest is still on course and still wiping out their ships.
Saba tells Naomi that there are 21 ships ready to evacuate Medina. While she's coding optimal order through the gates, she realizes 1 of the ships, the Lightbreaker, is a high-priority prisoner transport ship en route to Laconia and realizes it must be transporting Holden. She decides that instead of helping with the prison break, she'll go with Clarissa to make sure the sensors stay down.
Bobbie and Katria set a bomb, then wait outside the ship for a Laconian in power armor to walk into their trap. As soon as one does, they blow the bomb, snatch the dead marine in a net, and stow the armor in some luggage.
The Tempest fires an impossible number of missiles back at the attacking fleet and slowly starts to whittle the Sol defense force down. Some ships make suicide runs but the Tempest keeps coming. Eventually some railgun rounds hit People's Home and they're forced to dump core. Drummer gets a tight beam from Trejo asking her how many more of her people need to die before she'll surrender. She replies "zero" and tells the remaining ships to stand down.
Overstreet recommends to Singh that Jordao be arrested and interrogated with the others, and later given leniency when his sentence is passed, so they don't know he's the rat. They get a warning that the Rocinante has left the dock, so Singh orders The Gathering Storm to intercept immediately, even though it's not fully crewed. A riot breaks out in the prison area and marines arrive to take Singh to a secure location; however, their power armor shuts down and Singh runs and hides in a bathroom.
Bobbie, Amos, and an insertion team tether themselves to The Gathering Storm. Once it starts chasing the Roci, Amos tries to cut his way through the hull, but it keeps healing itself; he cuts larger and larger concentric circles as the crew dives in. Inside, Bobbie feints a attack on ops and tells Amos to take his team to engineering.
Naomi, Clarissa, and Jordao are intercepted by Laconian security when they try to sabotage the sensors; Jordao sold them out. All looks hopeless until Claire uses her implants to kill the guards and Jordao; however, she takes quite a bit of damage in the exchange, including a bullet, and in her weakened state, she can't survive her wounds.
Bobbie makes it to ops, and easily draws on the skeleton crew she finds there. She tells them they will all live if they surrender, so they do. They are given vac suits and enough air to survive a pickup, and Bobbie claims The Gathering Storm as her new ship.
The operation lasted 5 hours, and 20 ships got away. Singh decides the only way to stop this from happening again is to make a whitelist of citizens they know they can trust and cull the rest. Overstreet tells Singh that Trejo has given him orders to prevent anything that could further cause an insurgency, and tells Singh that he will be executed instead, to show that the people in power will be held responsible for their actions.
After Drummer surrendendered on behalf of the Transport Union, Earth and Mars quickly followed suit. Within months, other Laconian Protector-class destroyers moved into the Sol system to maintain order. Drummer is put under house arrest, almost like an enforced vacation. 3 months after the battle, the Heart of the Tempest arrives to take her away, and she's given a script to recite at the coming press conference. At the conference, Admiral Trejo tells her the plan is to shift the majority of Earth's population/culture to Laconia, so as to stop fetishising Earth. He invites her to join a permanent convocation of VIPs on Laconia. Avasarala suggests that Drummer play nice for the time being, though the shit's not over. She asks if Drummer knows why they're looking for Elvi Okoye, but Drummer is pulled away to give her presentation. After some deliberation, Drummer stays right on script.
The Roci crew sets down in Freehold, in a valley hidden by plants that release floating balloon-like bladders into the air. The colony is a 6-hour hike from their location. The locals were relatively welcoming, especially since the Roci brought Payne Houston back with them. Naomi gets data-dumps from Bobbie and they work to reverse-engineer how the Laconian technology works; it uses vacuum tubes instead of wiring, it has an excessive need for calcium, etc. Bobbie and her crew of Belters, with Amos as XO, are tucked away in an ancient lava tube on the moon of a gas giant in the system.
Duarte notices that as his child Teresa plays, he can see thought patterns around her head. He meets with Natalia Singh, who requests documentation on her husbands death, then goes to visit Holden in the brig. Holden is shocked to see that Duarte's been using the protomolecule on himself. Duarte tells Holden that he chose Laconia because the probes showed a ship that was already halfway-constructed in the orbiting structures. Holden says whatever killed the ring-makers took a shot at us on the Tempest, and that they need to stop using the technology; Duarte says the beings failed, because we're still here. He asks Holden to help him prepare to directly attack the beings that killed the protomolecule creators.
Review: 4 stars. I couldn't put the book down, but I'm still disappointed at how slowly we're being drip-fed new info about the protomolecule creators and the "others".
