Since the Sixties, the legendary exploits of Starfleet have captivated the hearts and minds of science fiction fans worldwide. To celebrate its success, Pocket Books decided that it would devise a series that would look back on the Trek franchise, and illustrate its popularity. This series was the ‘Signature Edition’ collection, each book collecting two or more reissues of Trek novels into one larger book. Now, in these two unique bundles representing this series in its finished form, prepare to boldly go forth into the fictional unknown, and experience the adventure within!!

Of all the experiences shared by Captain Kirk and the crew of the Starship Enterprise™ during their first five-year mission, two were among the most perilous: a journey to the nonphysical realm of Transition where the massive computer known as Memory Prime was situated, and the nightmarish mission to Talin IV, a world poised on the brink of destruction that Kirk was forbidden to save.

In the twenty-third century, a hundred years before a sentient artificial life-form would be allowed to earn a Starfleet commission, the Federation considers the use of self-aware artificial intelligences to be little more than slavery, except for the immense computer system of Memory Prime -- the key hub in the Federation's vast network of interstellar library planets. There, the A.I.s known as Pathfinders inhabit Transition -- a virtual world so different from our universe that the A.I.s themselves debate whether or not the physical universe is real. But when an ancient enemy reaches out from the shadows of Vulcan's darkest history and threatens to destroy the Federation, Spock must risk his career, and his life, to enter the Pathfinders' realm.

Technologically and politically, Talin IV is little different from late-twentieth century Earth. But as a series of mysterious events pushes that world closer to self-annihilation, the Prime Directive prevents Captain Kirk and his crew from doing anything to prevent it. When the worst appears to happen and Kirk takes desperate action to give the Talin a chance to step back from the nuclear abyss, Talin IV is consumed by radioactive fire. Now, with a world destroyed and the Enterprise dead in space, the careers of Kirk and his crew are over. Disgraced and despised, Kirk has only one chance to redeem himself and his crew: Somehow, he must make his way back to Talin IV and discover what really happened, even if it means proving that a world died because he broke Starfleet's most sacred law.

Imzadi: to the people of the planet Betazed, including Counselor Deanna Troi of the Starship Enterprise,™ it means "beloved" and denotes that which can never be truly broken.

Yet to whom does Deanna's heart truly belong?

Commander William Riker was the first Deanna called Imzadi. Long before they served together on board the Enterprise, they shared a tempestuous love affair back on Betazed. And even now, many years later, Riker will embark on a desperate journey across time and space to save Deanna's life.

But Riker is not the only Starfleet officer to capture Deanna's heart. Lieutenant Commander Worf, the fierce Klingon warrior, is also drawn to Deanna's gentle and caring nature. Brought together by fate, he and Deanna share an unexpected passion that tests the bonds between Troi and Riker -- even as a deadly Romulan conspiracy threatens them all!

This edition includes Imzadi and Imzadi II: Triangle.

The fiercest battles and proudest warriors throughout Klingon history are said to reflect the honor and glory of the race's first emperor, Kahless the Unforgettable. But history is not always truthful. And for both the Klingon Empire and the United Federation of Planets, the real truth may be too difficult to accept.

In the pages of a novel disclaimed by Starfleet, an enemy offers his perspective on events that transpired during the formative years of Klingon-Federation relations in the early twenty-third century. Chronicling the life story of Krenn, a Klingon war strategist who learns of peace while on a mission to Earth, the novel is a testimony to his efforts to preserve the honor of his people...by preventing total war against the then-struggling Federation.

Nearly a century later, a clone of the revered Kahless oversees the Klingon Empire. But when the myths and legends associated with the original emperor are disputed following the discovery of an ancient scroll, the new Kahless faces treason from within his own council, and impending civil war that could tear the empire apart. His sole chance for restoring his people's shattered faith must come from the outside -- specifically, from Captain Jean-Luc Picard and Lieutenant Worf of the U.S.S. Enterprise.
