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(TM) " 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(TM) " 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...
