Book 1

Within every federation and every empire, behind every hero and every villain, there are the worlds that define them. In the aftermath of Unity and in the daring tradition of Spock's World, The Final Reflection, and A Stitch in Time, the civilizations most closely tied to Star Trek: Deep Space Nine can now be experienced as never before...in tales both sweeping and intimate, reflective and prophetic, eerily familiar and utterly alien. CARDASSIA: The last world ravaged by the Dominion War is also the last on which Miles O'Brien ever imagined building a life. As he joins in the reconstruction of Cardassia's infrastructure, his wife Keiko spearheads the planet's difficult agricultural renewal. But Cardassia's struggle to remake itself -- from the fledgling democracy backed by Elim Garak to the people's rediscovery of their own spiritual past -- is not without opposition, as the outside efforts to help rebuild its civilization come under attack by those who reject any alien influence.
ANDOR: On the eve of a great celebration of their ancient past, the unusual and mysterious Andorians, a species with four sexes, must decide just how much they are willing to sacrifice in order to ensure their survival. Biological necessity clashes with personal ethics; cultural obligation vies with love -- and Ensign Thirishar ch'Thane returns home to the planet he forswore, to face not only the consequences of his choices, but a clandestine plan to alter the very nature of his kind.

Gateways #4

by Keith R.A Decandido

Published 2 November 2001
Once they moved from world to world in a single step, through innumerable doors that spanned the galaxy. They were masters of space, and to those who feared them, they were demons of air and darkness. But long ago they left their empire and their miraculous technology behind. Now someone has found the key to it, and all those doors have been þung open.

A world near Deep Space 9™, threatened with destruction from the distant Delta Quadrant, becomes the focus of a massive rescue effort as Colonel Kira Nerys, her crew, and some unexpected allies Þght to avert disaster on a planetary scale. Meanwhile, as Lieutenant Nog and Ensign Thirishar ch'Thane search for a way to shut down the spatial portals forever, Quark becomes involved in a dangerous game that could determine, once and for all, who will control the Gateways.

It is a time of renewed hope. As the U.S.S. Defiant sails through the wormhole and charts a new course of discovery into the unknown ocean of the Gamma Quadrant, powerful individuals from distant worlds gather at station Deep Space 9™ to usher in a bright new era; with the Dominion War now only a memory, Bajor is poised at last to enter the Federation. For Colonel Kira Nerys, Commander Elias Vaughn, and all those who follow them, these are the voyages they were born to undertake.

But where they seek to go is defined by the journeys they have made before, and ghosts populate these uncharted waters -- the spectres of lost leaders, fallen friends, forsaken lovers, vanquished enemies, and earlier selves. Some of these shades drive the travelers on, others are drawn inexorably into their wake; but all make their presence felt, and in feeling, the men and women of DS9 and the Defiant must somehow navigate the perilous rapids of their pasts in order to find the future.

Originally published as Twilight and This Gray Spirit -- the first two novels in the critically acclaimed Mission: Gamma series -- These Haunted Seas is the next chapter of the epic saga begun in Twist of Faith, continuing the chronicles of Star Trek: Deep Space Nine® beyond the small screen, propelling its heroes to realms they could never have imagined, and truths they cannot escape.

A four-book odyssey of space exploration, political intrigue, religious schism, deadly conspiracies and startling revelations, this is Deep Space Nine at its best.

Meanwhile those who remain on space station Deep Space Nine face incredible changes in their lives as the planet Bajor moves a major step closer to joining the Federation...

Travel to two of the most colorful and fascinating civilizations in the Star Trek universe with this collection of two sweeping and reflective novellas that transport us to the alien planets of Ferenginar and the Dominion.

In Ferenginar, Quark’s profit-driven home planet is rocked by a shocking scandal when allegations that Quark’s brother’s first wife has threatened to overthrow the Grand Nagus of the Ferengi Alliance, Rom. To make matters worse, Quark has been recruited by Rom’s political adversaries to join their coup d’état, with promises that all of Quark’s wildest dreams will come true if he helps. Quark must decide if the future of Ferenginar is worth his greatest desires or if he is strong enough to save it himself.

In The Dominion, the Great Link—the living totality of the shape-shifting Founders—has struggled with questions ever since its defeat in the war for the Alpha Quadrant. At its greatest moment of intense doubt, its fate, and that of the Dominion itself, is tied to Odo’s investigation of his kind’s true motives for sending a hundred infant changelings out into the galaxy.

As Odo searches for answers and takes a hard look at his past choices, Taran’atar reaches a turning point in his own quest for clarity—one from which there may be no going back.

Ascendance

by David R. George

Published 29 December 2015
The post-television Deep Space Nine saga continues with this original novel from New York Times bestselling author David R. George III!

On the original Deep Space Nine, Captain Kira Nerys watches as the nearby wormhole opens and discharges a single, bladelike vessel. Attempts to contact its crew fail, and the ship is soon followed by another vessel of similar design. When an armada subsequently begins to emerge from the wormhole, it seems clear that DS9 is under attack. Kira orders her first officer, Commander Elias Vaughn, to board the U.S.S. Defiant and defend the station, and alerts Starfleet to send additional forces as her crew prepares DS9’s shields and weaponry for the onslaught to come.

Meanwhile, on the lead ship, Iliana Ghemor considers launching an attack on DS9 and finally ending the life of Kira, the fountainhead of all the ills in her miserable life. Her vengeance demands more than mere death, though—it requires pain. Ghemor refocuses, choosing to follow her plan to mete out her revenge on the captain by first decimating the population of Bajor…

Original Sin

Continuing the Deep Space Nine saga—an original novel from New York Times bestselling author David R. George III!

At the end of 2385, in a significant shift of its goals from military back to exploratory, Starfleet sent Captain Benjamin Sisko and the crew of the U.S.S. Robinson on an extended mission into the Gamma Quadrant. Tasked with a yearlong assignment to travel unknown regions, they set out to fulfill the heart of Starfleet’s charter: to explore strange new worlds, and to seek out new life and new civilizations.

But now three months into the mission, their first contact with an alien species comes in the form of an unprovoked attack on the Robinson. With the ship’s crew suddenly incapacitated, seventy-eight of the 1,300 aboard are abducted—including Sisko’s daughter, Rebecca. But Rebecca had already been kidnapped years earlier by a Bajoran religious zealot, part of a sect believing that her birth fulfilled the prophecy of the arrival of the Infant Avatar. Does her disappearance now have anything to do with the harrowing events of the past? And for what purposes have these enemies taken Sisko’s daughter and the rest of the missing?

Hollow Men

by Una McCormack

Published 26 April 2005
At the turning point of the Dominion War, Captain Benjamin Sisko, facing certain defeat by the overwhelming and relentless forces of the Dominion, initiated a secret plan to secure the aid of the Romulans, the Federation's longtime adversaries. What began as a desperate attempt to save lives became a descent into an abyss of deception, moral compromise and outright criminal acts, as Sisko became compelled to sacrifice every ideal he believed in - in order to preserve those same ideals.
In HOLLOW MEN the aftermath of those events is explored as Sisko returns to Earth to answer for his actions. But to his surprise, no one intends to punish him. The course he took is viewed instead as a necessary and lesser evil which may yet prove to be the salvation of the Federation way of life. But Sisko's own conscience haunts him, and as he continues to seek some kind of penance for what he has done, opportunists within Starfleet itself set in motion a scheme which uses his actions as a springboard from which the Federation will emerge from the war as an imperial power.

THE DOMINION: Odo continues his efforts -- begun on DS9 -- to understand his shape-shifting people, The Founders, and why they felt driven to conquer the Federation. His quest leads him unexpectedly to questions about the gods and their creations ...and what those creations do when they believe that those gods have forsaken them. FERENGINAR: Political turmoil threatens to unseat Rom from the leadership of the Ferengi Alliance. A scandal involving criminal charges against Rom's former wife uncovers secrets which could not only bring him down but could undermine all the well-meaning changes his regime has introduced. Worse still, hardcore capitalist Quark has been enlisted by Rom's political adversaries to join forces with them against him, with promises of all the wealth and success Quark has ever dreamed of ...as long as he helps them to overthow his brother.
