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...

    The U.S.S. Enterprise, under the command of Captain Christopher Pike, responds. Starbase 18 lies in ruin. There are no survivors. And there is no clue as to who is responsible for the attack, until Captain Pike’s brilliant science officer discovers a means of retrieving parts of the station’s log. Lieutenant Spock has detected signs of a unique energy signature, one that he believes is Klingon. There are unsubstantiated reports that the Klingon Empire has made a technological leap forward and created a cloaking device—code-named Black Snow Seven—that can shield their ships from even the most advanced sensors. The destruction of the base and the unique energy signature that remains prove that the Empire has succeeded. For generations the Orions have been known as pirates,operating at the margins, outside of legal conventions. A proud and powerful race, the Orions were once a major force in the sector, and they have been using the tension between the Klingon Empire and the Federation to rebuild their power. Captain Pike is charged with trying to foster cooperation between the Orions and the Federation. A distress call from an Orion vessel offers him the perfect opportunity. But the Orion ship lies in disputed space long claimed by the Klingon Empire, and crossing it could be the spark that sets off an interstellar war.
