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.

    Kirk is the youngest man to be promoted to the rank of captain in Federation history. His crew consists of a first officer who finds him impetuous; a chief engineer who finds him arrogent; a chief medical officer who finds him trifling; and a helmsman who wants a transfer. But the young crew, which would later become the legendary space explorers, quickly puts aside their differences when a monstrous starship appears on their nascent flight path.

    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.

    On the planet Vulcan, a crisis of unprecedented proportion has caused the convocation of the planet's ruling council—and summoned the U.S.S. Enterprise™ from halfway across the galaxy to bring Vulcan's most famous son home in its hour of need. As Commander Spock, his father, Sarek, and Captain James T. Kirk struggle to preserve Vulcan's future, the planet's innermost secrets are laid before us, from its beginnings millions of years ago to its savage prehistory, from merciless tribal warfare to medieval court intrigue, from the exploration of space to the development of o'thia—the ruling ethic of logic. And Spock—torn between his duty to Starfleet and the unbreakable ties that bind him to Vulcan—must reconcile both his own inner conflict and the external dilemma his planet faces... lest the Federation itself be ripped asunder.

    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.

    Spock's mother, Amanda Grayson, is dying, and Spock returns to the planet Vulcan where he and Sarek enjoy a rare moment of rapprochement. But just as his wife's illness grows worse, duty calls Sarek away—once again sowing seeds of conflict between father and son. Yet soon, Sarek and Spock must put aside their differences and work together to foil a far-reaching plot to destroy the Federation—a plot that Sarek has seen in the making for nearly his entire career. The epic story will take the crew of the U.S.S. Enterprise™ to the heart of the Klingon Empire, where Captain Kirk's last surviving relative has become a pawn in a battle to divide the Federation... and conquer it. With Sarek's help, the crew of the Starship Enterprise™ learns that all is not as it seems. Before they can prevent the Federation's destruction, they must see the face of their hidden enemy—an enemy more insidious and more dangerous than any they have faced before...

    Worlds that believe in magic consider it Darkness's mightiest talisman; and worlds of science consider it a lost artifact of some ancient and forgotten race. Some say the Heart enables its possessor to control people's minds and to amass wealth enough for a dozen lifetimes, while others think it capable of raising the dead, perhaps even changing the flow of time itself. But to all, the location of this fabled object has remained a mystery, until now. An isolated archaeological outpost has suddenly stopped responding to repeated requests for information. Sent to discover why, the "U.S.S. Enterprise" TM crew finds a devastated outpost and a dying scientist, whose last words fall on disbelieving ears: the Devil's Heart has been found. As the quest for the Heart unfolds, Captain Jean-Luc Picard discovers that beyond all the legends and age-old secrets lies an awful truth: whoever holds the Devil's Heart possesses power beyond imagining.

    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 ... ?

    For his part, Captain Spock must make the toughest decision of his Starfleet career.

    Leonard McCoy thought he had it all. But when the woman he loved betrayed him, McCoy fled to Starfleet, hoping to lose his pain in the depths of space. Now, more than forty years later, the "Enterprise"TM and her crew are ordered to transport a group of mediators to the planet Ssan, a world where assassination is a time-honored tradition, and McCoy is surprised to learn that his ex-wife, now remarried, is one of the mediators. And before he can come to terms with his conflicted feelings for his former love, she and Captain Kirk are trapped on Susan, and McCoy is caught in an explosive civil war, the only one with the power to save the woman who once nearly destroyed him.

    But Kirk, McCoy, Scotty and the crew join forces again on the Enterprise to thwart an incredibly destructive power—a threat to earth and the human race. This novel is written by the creator of Star Trek, Gene Roddenberry.

    Now, as an ancient and forbidden technology tempts mankind once more, Captain James T. Kirk of the Starship Enterprise™ must probe deep into the secrets of the past, to discover the true origins of the dreaded Eugenics Wars—and of perhaps the greatest foe he has ever faced. 1974 A.D. An international consortium of the world's top scientists have conspired to create the Chrysalis Project, a top-secret experiment in human genetic engineering. The project's goal is nothing less than the creation of a new, artificially improved breed of men and women: smarter, faster, stronger than ordinary human beings, a super-race to take command of the entire planet. Gary Seven, an undercover operative for an advanced alien species, is alarmed by the project's objectives; he knows too well the apocalyptic consequences of genetic manipulation. With his trusted agents, Roberta Lincoln and the mysterious Isis, he will risk life and limb to uncover Chrysalis' insidious designs and neutralize the awesome threat that the Project poses to the future. But he may already be too late. One generation of super-humans has already been conceived. As the years go by, Seven watches with growing concern as the children of Chrysalis—in particular, a brilliant youth named Khan Noonien Singh—grow to adulthood. Can Khan's dark destiny be averted—or is Earth doomed to fight a global battle for supremacy? The Eugenics Wars: Volume One is an engrossing and fast-paced thriller that explores the secret history of the twentieth century—and the rise of the conqueror known as Khan.

    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!

    In their relentless quest for technological perfection, they have destroyed entire star systems, enslaved countless people, and, in a single brutal attack, decimated Starfleet's mightiest vessels. Answering a distress call from a planet under attack by the Borg, the U.S.S. Enterprise meets Delcara, the lone survivor of an alien race the Borg obliterated. Blinded by hatred, Delcara seeks the ultimate revenge, the complete destruction of her race's executioners. But the U.S.S. Enterprise crew learns that Delcara's vengeance carries a terrible price, for once unleashed, the destructive force she commands will annihilate not only the Borg, but countless innocents as well.
