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.

    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.

    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.

    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.

    Starfleet has just been founded and the Enterprise has just been built, and is sent on its first mission. The mission takes the Enterprise into the heart of hostile Romulan territory, where cosmopolitical machinations and advanced weapons technology will decide the fate of a hundred innocent worlds.

    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.

    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.

    In the years since, Q has returned again and again to harass Picard and his crew. Sometimes dangerous, sometimes merely obnoxious, Q has always been mysterious and seemingly all-powerful. But this time, when Q appears, he comes to Picard for help. Apparently another member of the Q continuum has tapped into an awesome power source that makes this being more powerful than the combined might of the entire Q continuum. This renegade Q is named Trelane -- also known as the Squire of Gothos, who Captain Kirk and his crew first encountered over one hundred years ago. Q explains that, armed with this incredible power, Trelane has become unspeakably dangerous. Now Picard must get involved in an awesome struggle between super beings. And this time the stakes are not just Picard's ship, or the galaxy, or even the universe -- this time the stakes are all of creation...

    Now de Lancie and Peter David, the bestselling author of such acclaimed novels as Q-in-Law and Q-Squared, have joined forces to send Q on an unforgettable cosmic odyssey, told from the mischievous trickster's own unique point of view. The Maelstrom, a metaphysical whirlpool of apocalyptic proportions, is pulling all of reality into its maw, devouring the totality of time and space while bringing together people and places from throughout the universe. The Q Continuum pronounces that the end of everything has come, but Q refuses to meekly accept the end of all he has known. Defying the judgment of the Continuum, he sets out to derail doomsday—at whatever the cost. Q has been everywhere and done everything, but now he's in for a cosmic thrill ride beyond even his own astonishingly unlimited imagination. Old friends and adversaries wait in unexpected places, transcendent hazards abound, and the multiverse's most unlikely savior encounters wonders and dangers enough to render Q himself speechless. Almost. Can even Q, reluctantly assisted by Jean Luc Picard, prevent the Universe as We Know It from literally going down the drain? I, Q is a wild and witty voyage through the secret soul of creation—as only Q can tell it!
