    One of the most popular and compelling Star Trek characters ever created, Dax is a wormlike being who is joined body and soul to a succession of humanoid hosts. Each life is different, each body is different, each personality is different, but all of them are Dax. At one time or another Dax has been male, female, a Starfleet officer, a statesman, a scientist, and ambassador, even a serial killer. The symbiont's humanoid hosts have included Curzon, friend of Klingons, and Jadzia, science officer on Deep Space Nine and latterly wife of Worf. The most recent incarnation is Ezri Dax, station counsellor on Deep Space Nine. Designed to appeal to fans of every version of Star Trek, the stories in The Lives of Dax each show a different host's adventure—nine incredible lives stretched out over 357 years of Star Trek history.

    When it is uncovered, the very heart of the Federation will be ripped apart! Only the crew of Deep Space 9 can stop it but will they have time?

    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.

    But when an alien spacecraft crash-lands in the South Pacific bearing visitors from another world, the Vulcans, Earth must decide whether to extend the hand of friendship, or the fist of war. In the distant future, horrible dreams torment Admiral James T. Kirk, dreams prompted by his reading of Strangers from the Sky, a book about that historic first contact. He dreams of an alternate reality where he somehow changed the course of history, and destroyed the Federation before it began.

    Humanity’s greatest dreams have become reality. Along with dozens of other sentient races, the people of Earth have formed the United Federation of Planets—a galactic civilization that governs much of the known universe for the good of all. Over the past two centuries, mankind has tamed its basest instincts, and reached the stars…But suppose it hadn’t happened that way at all? Suppose instead humanity’s darkest impulses, its most savage, animalistic desires had triumphed? Suppose that the empire mankind made out in the stars was one ruled by terror, where only those willing to brutalize their own kind and their neighbors could survive?One hundred years ago, four crewmembers of the U.S.S. Enterprise crossed the dimensional barrier and found just such an empire. A mirror image of their own universe, populated by nightmare duplicates of their shipmates. Barely able to escape with their lives, they returned thankful that the accident that brought them there could not be duplicated. Or so they thought.But now the scientists of that empire have found a doorway into our universe. Thier plan: to destroy from within, to replace one of our starships with one of theirs. Their victims: the crew of the U.S.S. Enterprise NCC 1701-D.

    Now they want them back....Captain Kirk is stunned when the Federation receives an urgent plea for help -- from the Klingon Empire. A mysterious starship has invaded Klingon space and resisted all their efforts to destroy it. Establishing contact with the stranger's ship, Kirk discovers that it is only the vanguard of a vast alien fleet obsessed with conquering the Klingons, the Federation, the Romulans, and all who dwell in the space that was once their own.The Invasion has begun....

    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.
