    After their existence was discovered in 2151 by Captain Jonathan Archer of the "Starship Enterprise"(TM), all Starfleet vessels were warned to keep an eye out for these most dangerous devices...One hundred years later, Captain James T. Kirk of the "U.S.S. Enterprise" and Commodore Matt Decker of the "U.S.S. Constellation" come across the first artifact on the colony world of Alpha Proxima II -- a world ravaged by a mysterious plague. As the crews of the two mighty vessels work to find a cure and locate the artifact, two brave captains must bring order to Proxima before it's too late!One hundred years after that, Commander Benjamin Sisko of Station Deep Space 9(TM) enlists the aid of Captain Declan Keogh of the "U.S.S. Odyssey" to help construct a farming colony on Bajor's second moon -- but the colony is placed in jeopardy when the Bajoran terrorist Orta discovers the second artifact and threatens destruction on a massive scale!

    Left behind by a long-vanished civilization, these mysterious portals offer a means of exploration -- or conquest -- many times faster than warp travel. The technology responsible for the Gateways has been lost for at least ten millennia, but that doesn't mean it can't be found again.... Having defeated the hostile computer program guarding an abandoned Kalandan outpost, Kirk and his crew are exploring the artificial planetoid in hopes of discovering the secret of an ancient apparatus that has hurled the "Starship Enterprise(TM) " over nearly a thousand light-years. Unfortunately, the reactivated Gateway has attracted the attention -- and avarice -- of various alien explorers, including a mysterious race who claim to be none other than the enigmatic Kalandans themselves

    But while her exploits are legend, little has been revealed about Rachel Garrett, her vessel, or the unusual men and women of her crew. Until now. When the archeological find of the decade hints at an earlier Cardassian civilization, it attracts not merely academics and knowledge-seekers but also those with far less noble interests. Among them is Asfar Qatala, a notorious criminal cartel with a disturbing connection to one of the highest-ranking officers on the Enterprise. Captain Garrett and her crew find themselves swept in to a maelstrom of kidnapping, extortion and murder -- as well as a desperate, secret struggle between the Qatala and its chief rival, the fledgling Orion Syndicate. And beneath the surface of the frozen world on which the proto-Cardassian discovery was made, another drama is playing out that will force Captain Garrett to make the most difficult decision of her career...amid ruins reputed to link the living with the dead.

     A vicious pirate known as the Albino is cutting a deadly swath across space, creating turmoil in the Klingon Empire that threatens to spill into the Federation. But this criminal also has a secret that could shake the halls of Imperial power, and his genocidal plans against the race that bore him will have consequences even he cannot imagine, as several unlikely allies join swords to bring the Albino to justice: Hikaru Sulu of the U.S.S. Excelsior; Klingon captains Kor, Koloth, and Kang; and a hotheaded young Federation diplomat named Curzon Dax. Tempered in the flames of their shared adversity, a captaincy is forged, a Blood Oath is sworn...and a hunt begins that will stretch from one generation to the next.

    Its most honored captain is in disgrace, its most celebrated starship in pieces, and the crew of that ship scattered among the thousand worlds of the Federation... Thus begins Prime Directive, an epic tale of the Star Trek universe. Following in the bestselling tradition of Spock's World and The Lost Years, Judith and Garfield Reeves-Stevens have crafted a thrilling tale of mystery and wonder, a novel that takes the Star Trek characters from the depths of despair into an electrifying new adventure that spans the galaxy. Journey with Spock, McCoy, and the rest of the former crew of the Starship Enterprise to Talin—the planet where their careers ended. A world once teeming with life that now lies ruined, its cities turned to ashes, its surface devastated by a radioactive firestorm—because of their actions. There, they must find out how—and why—this tragedy occurred and discover what has become of their captain.

    Spocks! One is the true First Officer of the Enterprise. The other is his complete opposite, a traitor whose very existence poses a grave threat to the crew, the ship, and the Federation itself. One of the Spocks must die. But which one ... ?

    Among the changes were William Riker's promotion to captain and his new command, Riker's marriage to Counselor Deanna Troi, and Dr. Beverly Crusher's new career at Starfleet Medical. But the story of what set them on a path away from the Starship Enterprise™ has never been told. UNTIL NOW. The site of one of the Dominion War's fiercest battles, the Rashanar Sector now contains a vast interstellar graveyard littered with the lifeless hulks of hundreds of devastated starships. The explosive destruction of so many varied warp drives has severely distorted the space-time continuum in this region, resulting in dangerous unleashed energies and bizarre gravitational anomalies. The Enterprise has been assigned to patrol the perimeter of the danger zone, while other vessels carry out the difficult and highly hazardous task of retrieving the bodies of the dead from the wrecked warships. To some alien races, the former battleground is hallowed space. To others, including the rapacious Androssi, it is a scavenger's paradise, ripe for salvage. None expect this ship's graveyard to hold a deadly secret that will force the android Data to make a heart-wrenching decision about the path his life will take -- and that will endanger not only the Enterprise, but Picard's future in Starfleet.

    Spock, and Dr. McCoy struggle to establish new lives apart from each other and the starship. The newly-promoted Admiral Kirk is placed in charge of a specially-created Starfleet division and attempts to defuse a critical hostage situation; Mr. Spock, who, in the midst of a teaching assignment on Vulcan, finds the one thing he least expected; and Dr. McCoy, whose unerring instinct for trouble lands him smack in the middle of an incident that could trigger an interstellar bloodbath.

    Dauntless, Captain Kathryn Janeway's indefatigable crew continues their odyssey of discovery through an enigmatic region of the Delta Quadrant, encountering a system inhabited by a species that, according to known physical laws, shouldn't exist.These unusual beings, the Monorhans, hover near the edge of extinction; technology from the Starship Voyager(TM) promises life. Janeway, compelled by the aliens' plight, dispatches Seven of Nine and Lieutenant B'Elanna Torres to the Monorhan homeworld. But an unexpected shock wave crashes the shuttle carrying Torres and Seven, catapulting Voyager into a place beyond the fabric of space-time.As B'Elanna and Seven wage an interpersonal war, Voyager struggles to prevail on an extradimensional battleground against an indefinable enemy. But fate has determined that one is inexorably linked to the other: the insurmountable chasm separating Voyager from her lost crew members must be bridged...or all will perish.

    Their victory sent shock waves through the Alpha Quadrant, and put the Dominion within striking distance of Vulcan, Andor, Tellar -- and possibly Earth itself.To secure their position in the very heart of the Federation, the Cardassians begin constructing the space station Sentok Nor in orbit of Betazed. The station is to serve as both the seat of the Dominion occupation and the site of horrific experiments by Cardassia's foremost exobiologist, the infamous Dr. Crell Moset. With Starfleet's forces spread too thinky in the ongoing struggle to retake Betazed outright, the U.S.S. Enterprise along with some old and new friends, is deployed to carry out a dangerous and desperate plan. But no matter what the outcome, the consequences could alter Betazed irrevocably, forcing Deanna Troi to choose between her world's survival and its very soul.

    Enterprise™ journeys through the Taurus Reach, a vast and little-known region of space in which a new starbase has been unexpectedly established. Puzzled by the Federation's interest in an area so far from its borders and so near the xenophobic Tholian Assembly, Captain James T. Kirk orders the Enterprise to put in for repairs at the new space station: Starbase 47, also known as Vanguard. As Kirk ponders the mystery of the enormous base, he begins to suspect that there is much more to Vanguard than meets the eye. It's a suspicion shared by the Tholians, the Orions, and the Klingon Empire, each of whom believes that there are less than benign motives behind the Federation's sudden and unexplained desire to explore and colonize the Taurus Reach. But when a calamity deep within the Reach threatens to compromise Starfleet's continued presence in the region, Kirk, Spock, and several key specialists from the Enterprise must assist Vanguard's crew in investigating the cause of the disaster and containing the damage. In the process, they learn the true purpose behind the creation of Vanguard, and what the outcome of its mission may mean for life throughout that part of the galaxy. Inside: Bonus diagrams of Vanguard station!
