Commander Benjamin Sisko is just recovering from the death of his wife when he is assigned command over the former Cardassian, but new Federation space station, Deep Space Nine^TM. This space station is strategically located not only because of its orbit about Bajor, but also because of its proximity to the only known stable wormhole in the galaxy. After meeting the other Bajoran and Starfleet personnel assigned to the station, including a former Bajoran freedom fighter and a shapeshifter, Sisko finds himself in that very wormhole and in the midst of a metaphysical experience as the alien inhabitants of the wormhole question the concepts of time and love. Sisko, filled with humanistic hubris, begins to explain these experiences, and resolve his painful past. END

Deep Space NineTM is forced to curtail entry to the wormhole due to increased graviton emissions, and an air of biting tension settles over the station. This anxiety leads to the murder of an Edeman religious leader, Commander Benjamin Sisko and Security Chief Odo realize they face a larger problem. Soon Sisko and Odo have more lifeless bodies on their hands and a killer who strikes without motive. Then, both the Edemans and Cardassians arrive threatening to destroy the station unless the murderer is given to them for retribution. In order to save Deep Space Nine and stop the killing, Odo must try to destroy a powerful assassin who is the only link to his mysterious past.

Starfleet Command has learned that the Cardassians are planning to construct a base on the other side of the wormhole to establish a presence and claim the rich unexplored territory. Now, it falls to Commander Sisko, Major Kira, and the crew of Deep Space Nine^TM to set up a Federation station there immediately.

Before Major Kira can deliver the new base, a fanatic from her violent past appears. Kira must engage in a life and death struggle with an enemy who will stop at nothing to destroy her, as the fate of Bajor, the wormhole, and possibly the entire Federation hangs in the balance.

When Quark holds a poker tournament on Deep Space Nine^TM someone from almost every sentient race — Klingons, Cardassians, Romulans, Vulcans, Ferengi — shows up for what is sure to be the highest-stakes game of all time. But when one player is killed, the stakes get higher than even these big-money players had counted on.

With the station rocked by subspace waves that threaten its destruction, Commander Sisko and Security Chief Odo must hunt down the killer in time to save the players, a killer who has information that can save those onboard Deep Space Nine from the invisible enemy they do not even know they face, a killer who holds all the cards.

When a troop of alien warriors demands the return of an imprisoned comrade — a prisoner no one on Deep Space Nine^TM knows anything about — Commander Benjamin Sisko has a deadly fight on his hands. Under sudden attack from the heavily armed warriors, Sisko and his crew struggle desperately to repel the invaders and save the lives of everyone on board. Meanwhile, a strange device from the Gamma Quadrant has shifted Ferengi barkeeper Quark and Security Chief Odo three days into the future to a silent Deep Space Nine. To save the station they must discover what caused the invasion to take place, and find a pathway back through time itself.

Ambassadors from all over the Federation have assembled on Deep Space Nine^TM for a conference that will determine the future of the planet Bajor. Keeping dozens of ambassadors happy is hard enough, but soon terrorists begin a bombing campaign on the station, and Commander Sisko’s job becomes nearly impossible. Distracted by all of this, he’s in no position to deal well with the arrival of a belligerent Cardassian commander demanding the return of Deep Space Nine to the Cardassian empire, but he must rise to the occasion if his station and Bajor are to emerge from the crisis intact.

A message left behind by the Kai Opaka gives Commander Benjamin Sisko a fateful mission: find a young Bajoran girl destined to be a great healer who could bring together the warring factions of Bajor. While Lt. Dax tries to find the healer, Dr. Bashir goes planetside to treat a rare disease that is killing the children in Bajor’s resettlement camps. Surrounded by thousands of dying children, Bashir goes A.W.O.L. from Deep Space Nine TM, vowing not to return until the plague has been stopped. But by the time Dax finds the girl from the Kai’s prophecy the child has fallen victim to the plague. Now, with the fate of the entire planet at stake, Commander Sisko must find Dr. Bashir in time to save the child who may be Bajor’s last chance for peace.

The Bajoran shipyard is assigned to build an engine for a new starship, a project which could be instrumental in revitalizing the planet’s war-ravished economy. As Commander Sisko awaits the arrival of a tanker containing the antimatter that will power the starship, a band of hijackers captures the extremely valuable cargo and escapes through the wormhole.

When the hijacking spurs a political debate, Major Kira struggles to mediate the dispute between the opposing factions. Meanwhile, Sisko makes a desperate move to retrieve the antimatter. With the stability of the Bajoran economy at stake, Sisko, Dax, and Odo infiltrate the hijackers, a move that could have deadly consequences for them and the planet Bajor.

The free flow of traffic to the Gamma Quadrant is vital to the recovery and survival of the planet Bajor and to Federation interests as well. When a mysterious cloaked ship begins raiding wormhole shipping, cleaning out holds and killing entire crews, Commander Benjamin Sisko of Deep Space Nineâ„¢ acts at once to stop the menace.

Commander Sisko has unexpected aid: the cloaked vessel has been striking Cardassian ships as well, and the Cardassian commander Gul Dukat intends to destroy the ship at all costs. Their unlikely alliance works well — until two of Sisko’s crewmen are captured by the raiders. Gul Dukat will stop at nothing to gain his victory; now Sisko must locate the predator ship, hold off the Cardassians long enough to rescue his people — and prevent an interstellar war!

Tensions caused by speculation that Cardassia is about to reoccupy Bajor are complicated by the arrival of a strange alien ship. When it’s discovered that the crew is dead and the ship is carrying valuable Gamma-quadrant technology, it becomes a sought after prize, which Commander Sisko must fight to keep out of Cardassian hands. Meanwhile, Sisko also finds himself at odds with Major Kira, who believes the ship is Bajoran property.

When the alien ship suddenly seizes control of Deep Space Nine^TM, and the Cardassians move in to try to capture it, Sisko must face off against a shipload of angry Cardassians, and the alien being controlling Deep Space Nine.
