Summary: Delta Quadrant: The supertanker Apsac is attacked by a Hirogen vessel. Their tank of theta radiation is damaged and about to rupture, but suddenly a hole in space, some sort of gateway, opens directly ahead of them. In a last ditch effort to avoid poisoning the entire star system, they jettison their antimatter waste payload into the hole, destroying the Hirogen ship in the process.
Gamma Quadrant: Nog and Shar bring the new communications array online, reestablishing communications between the Alpha and Gamma Quadrants. Kira immediately summons the Defiant back to DS9 for a meeting with Admiral Ross; there is an emergency on Europa Nova, wherein massive amounts of theta radiation have suddenly been ejected into the system. As soon as they get back to the station, a message comes through the array from a civilian ship that had been on the Terran system; they have no idea how they wound up in the Gamma Quadrant. Commander Vaughn says not to worry, that they'll dispatch a runabout to lead them through the wormhole.
Kira and Vaughn attend a holoconference with many of the top Starfleet commanders and Admiral Ross, who says outfits Iconians approached the Federation Council. Captain Picard explains that the Iconians lived over 200 millennia ago, with their home planet being in the Romulan Neutral Zone. They invented gateways that would allow instantaneous travel across light-years. The Iconians have offered up their gateway technology to the highest bidder, and as a demonstration, they've activated all of them. Montgomery Scott, head of the SCE, says studies show that the gateways, once they've expended their energy, will tap into any nearby sources for power--including stars and planets.
For some reason, the wormhole seems to be preventing any gateways from opening with 10 lightyears, so Kira and Vaughn are tasked with researching why. Vaughn had previous experience with a gateway in a classified mission. Ross says the Intrepid and the Gryphon are en route to DS9 to assist with the Europa Nova disaster. The Bajorans are also sending a fleet, and Kassidy Yates, who is on DS9 for a checkup with Dr. Bashir, also volunteers her ship, the Xhosa, giving them about 20 ships total. They have 52 hours before the theta radiation exposure is fatal.
Vaughn tasks Nog and Shar with figuring out why there are no gateways near the wormhole, Ezri will stay on DS9, Vaughn will take the Defiant, and Kira is taking the Euphrates, with Taran'atar in tow.
Farius Prime: Malic of the Orion Syndicate has brought Quark in to negotiate with the Iconians for control of the gates. Quark is shocked to find his cousin Gaila is negotiating on behalf of the Iconians. After the initial round of talks, Quark learns from Malic that there are no gates near the whole and uses this to strengthen his bargaining position.
Someone named Kam tells another named Hig to go figure out why there are no gates by the wormhole; he says the longer the Ferengis negotiate, the higher the chance of the illusion slipping.
Shar and Nog run all the scans they can, without finding a correlation between the wormhole and the lack of gateways; until they realize that a gateway actually has opened with 10 lightyears on the Game Quadrant side. Shar then remembers the Denorios Belt is know for its heavy tachyon eddies, and they surmise that that is what's preventing the gates. They report their findings to Ezri, and just as they're about to return to DS9, they're attacked by an unknown, much larger, ship that knocks out their shields and disables them.
Kira arrives at Europa Nova and speaks with their president, Silverio Grazia, who says they've already evacuated the planet's children. She says Councilor zh'Thane is there, and should be evac'ed next, so Kira has her beamed aboard the Defiant. She says after everyone is evacuated, they'll devise a way to restore the planet. Taran'atar doesn't understand why they care about the planet, as they can just find a new one; Kira explains that it's because it's their home. He says for the Jem'Hadar, their unit is home, not a planet. She can tell he was affected by his trip to Sindoren.
The Defiant detects a gateway on the planet, in a coastal town named Costa Rocosta. Vaughn goes to check it out and finds that it leads to Torona IV, home of a rather xenophobic species called the Jarada. Kira tells Vaughn he just negotiate with them to harbor Europani citizens, as the ships won't be able to transport them in time. Though they will not allow it at first, Vaughn eventually convinces them to let 500,000 people through for the exchange of information about the gates--though they say that if anyone strays from the allotted zone, or more than the agreed upon number come through, they will be executed. Vaughn agrees to the terms.
Just as the runabout Sungari is about to explode, the Defiant arrives and destroys the unknown enemy ship. They beam Nog and Shar aboard just as the runabout's core breaches. Shar runs into his zhavey, she Vretha says that after the crisis is over, they need to talk.
A large, irradiated meteorite comes through the gate, and Kira uses her roundabout's tractor beam to divert it from a population center into a once thriving lake. She gets a message from Vaughn saying that Shar and Nog have modified the Defiant's deflector to emit a tachyon burst that should disable all gateways of used on just one of them. She punts the decision to Admiral Ross, and in the meantime, decides to go through the gate to stop the radiation at the source. However, the Cardassian ship Trager arrives in the system, and when she hails them, she is greeted by the face of Dukat.
Kam receives a report that Higs's ship was destroyed while attacking the Starfleet vessel. Kam says the Orion deal is still in negotiations, and that it's orders of magnitude better than all other offers.
Quark is hoping to draw the negotiations to a close, but Gaila tells the Orions that Quark is working to stall their talks on behalf of Starfleet so his nephew Nog can close the gates. Malic says if Quark doesn't tell him the truth, he's dead, so Quark tells him that he is working for Starfleet. Malic tells his guards to kill him anyway.
Gul Macet explains to Kira that he is Dukat's cousin, and that he's here to help; he says his ship is in such bad shape because he was helping Damar's resistance destroy the cloning facilities on Rondac III. She reluctantly agrees to his help, and says that since his ship is equipped with more advanced Dominion transporters, he should begin beaming up survivors; he says Cardassians will likely not be welcomed by the Europani, as they have a "history." Kira contacts President Silverio who is vehemently against their help; she says the asteroid belt in their system used to be a planet that the Cardassians destroyed. Kira eventually gets her to relent by telling her that a lot of people may die without their help.
Ezri gets a call from Dr. Renhol of the Trill Symbiosis Commission, who she's supposed to contact weekly--but hasn't for 6 weeks now. The doctor is concerned to find that Ezri has switched to the command track without consulting them, but Ezri writes her off and says that with the ongoing crisis, she doesn't have time to talk. While making the rounds, she finds herself switching personas and screaming at a Europani woman, and thinks that maybe the doctor had a point--but chocks it up to not having slept for 50 hours.
Ezri rounds a corner and overhears Shar arguing with his zhavey Vretha, who wants him to return to Andor. He tells her that he's working another angle on their dying species, and that he will not. Shar turns and runs straight into Ezri. Vretha blows her off, and Shar says that she may try to get Vaughn to reassign him to Andor; Ezri says she doubts that would happen, but Shar says she doesn't know the extent of his zhavey's influence.
Kira and Taran'atar travel through the gate and find the ship dumping waste through it. They hail it, but are met with weapons fire that knocks out their shields. Kira awakens aboard the enemy vessel to find its crew cut into pieces, and a Hirogen says only "prey" to her.
Just as Malic is about to kill Quark, his dabo girl Tamra, who is actually Ro Laren, throws one of her waist tassels on the ground, detonating a flash grenade, and they make a run for it.
Quark had approached Ro weeks before, asking for help with the Orions, afraid that they would rat him out to Garak; Quark has been working with a Cardassian named Deru to illegally divert relief supplies to wealthy patrons in exchange for land. She agrees to help Quark, but only if he helps her infiltrate the Orion Syndicate; otherwise, she's going to tell both Starfleet and Garak about what he's been doing.
Ro takes an Orion slave girl named Treir hostage, and they use her to get past a squadron of Orions, who would never sacrifice such valuable merchandise. Ro activates a beacon and they're beamed onto a Bajoran Militia flitter near Farius Prime's innermost moon. Ro reveals that she also nabbed Malic's padd when she threw the flash grenade, so the evidence against Quark is theirs--unless he made a backup.
The Hirogen tells Kira that she is bait for the other from her ship; just then Taran'atar unshrouds and attacks him. He and Kira flee, trying to find their way to the transporters. Along the way, they stumble across the ship's shield enhancer, which is similar to those that Bajoran ships used; Kira says they need to take it to shield their runabout against the enormous mass of radiation about to go through the gate. Taran'atar beams her back to their ship, resolved to stay behind to fight the Hirogen. Right before, he tells her that he thought his gods had cast him out, but he was wrong.
Back on the Euphrates, Kira finds that the enhancer won't have enough power unless she shuts down life support, so she records a message explaining that she's going to a nearby class M planet, sending the shuttle on autopilot through the gate to shield against the radiation, and tells them to close the gate on her if they find a way to. The shuttle drops her off near a lake, but the planet is mostly a desert. She begins building a shelter as the radiation starts to poison the sky.
Vaughn gets a report from Costa Rocosta that a Europani is holding people and 6 cases of radiation meds hostage, demanding that he and his family be allowed through the gate to Torona IV. Vaughn goes down to the surface and negotiates with the man, who is terrified of space travel. With little time to lose, Vaughn simply stuns him with a phaser, then tells Bashir to make sure the man stays sedated for his trip to space. Back on the Defiant Vaughn tells Nog to follow Kira's orders and initiate the tachyon burst; both the gate above the planet and the one on the surface deactivate.
Kira, with only 2 hours left before she succumbs to the radiation, gets a notification on her tricorder that indicates a gate has opened nearby. She trudges through the desert, collapsing from heat exhaustion multiple times, but makes it to the gate; it flashes back and forth between DS9 and the realm of the Prophets. Before she can choose when to enter, it closes. Her skin covered in blisters, and she is certain she's going to die.
Ro and Quark try to escape through the gateway near them, and it closes. The Orions see them and begin pursuit.
Taran'atar shrouds and stalks the Hirogen until he finds the right moment to attack; then stabs him in the face with his blade, causing it to drop its rifle. This doesn't kill it however, and they engage in a protracted fight, with the larger, faster foe constantly attacking Taran'atar with an arm-mounted blade. The Hirogen eventually manages to stab Taran'atar through the arm, and Taran'atar retaliates with another stab to its face. Eventually, he maneuvers it into stabbing a console, and while it's stuck, Taran'atar goes for it's dropped rifle; however, it breaks free and tackles him at the last second, then drives it's broken blade into Taran'atar's chest.
Kam tells Gen to get the gateways back online before the Orions discover their deception.
Malic checks his pockets for his padd and finds it gone. He puts out a bounty of 100 bars of gold-pressed latinum to anyone who gets it back, then goes to ask the Iconians why all the gates are offline. Shortly into their discussion, the gateways reboot and come back online, but the Orions are able to crack the communications between the Iconians onboard and their ship.
Quark manages to break the Iconian's codes as well; they intercept their com chatter and learn that they're not Iconians at all, but a race called the Petraw.
Malic tells the Iconian named Kam that he's a charlatan, and orders him and Gaila to be killed. Kam says he's been in subvocal communication with his ship, and that they will destroy Malic's ship.
Ro takes the flitter through the gate, and Quark beams Gaila off the Orion ship, right before it's destroyed by the Petraw vessel--which itself is nowhere to be seen. Quark says Gaila owes him another life debt as they head back to DS9.
The last of the Europani are evacuated from the planet and a cheer goes up; Prynn even smiles at her dad. Vaughn orders Lt. Bowers to stay behind and listen for a transmission from Kira while the refugees are taken to DS9 and Bajor. Vaughn asks Macet why he came to help, and The gul recalls the time that the Enterprise helped him track down former Starfleet Captain Ben Maxwell, who went rogue, destroying Cardassians ships. He says Maxwell was actually correct that the Cardassians were smuggling weapons, and that Picard knew it too, but decided to keep the peace anyway. He says the Cardassians need to work with their neighbors if they ever want to return to their former glory, and hopes this can be the first step.
Quark's partner Deru on Cardassia Prime receives a house call from a notorious former member of the Obsidian Order, Garak.
Back on the station, Treir complains to Ro that thanks to Ro taking her hostage, she's given up a life of luxury for no life at all. Quark says he has a perfect solution: she can work as a dabo girl at his bar. As they're walking away, Treir tells Ro the encryption algorithm for Malic's padd. Back in his bar, Quark receives a terrifying message: Garak says Ro kindly pointed him in the direction of Quark's friend Deru, who has unfortunately and suddenly fallen on hard times. He says Deru tried to blame Quark for his illicit dealings, but Ro vouched for him. He says they can talk about it at a later date.
The Hirogen pulls his blade out of Taran'atar's chest and is just about to leave for an escape pod when Taran'atar kills him with his own rifle. The computer detects a weak Bajoran lifesign on a nearby planet, but then it winks out. Taran'atar makes it to an escape pod and back through the gate, where he's picked up by Bowers. Taran'atar tells them that Kira is dead, then collapses.
The gateway opens back up, again flashing between DS9 and the Prophets. Knowing that she's already been exposed to a lethal amount of radiation, she makes her choice and goes through.
Review: 3.5 stars. I skipped this when reading through the DS9 stories, assuming it was a side story and not part of the ongoing continuity, so I already basically knew what was going to happen (obviously, that's my fault). The story itself was fine, but not super-captivating, and it's very lame that the ending is in book 7. There was some character growth that would've seemed less accelerated in the Mission Gamma series that follows, but really you can skip this one without missing much.
I'm curious if the other Gateways novels not set in the same time period even have anything to do with this one? Because this seemed fairly standalone.
