An unimaginable conflict could cost Kirk's soul...or Spock's life.

A dark plan has been unleashed in the galaxy, a design so vast, only a collective—and ruthless—mind like the Totality could have conceived it. Now Captain Kirk must battle the seductive force of the Totality's will. It was reasonable that Captain Kirk and Federation Free Agent Sola Than would fall in love. But no reasoning the the universe could have foreseen the tragedy of Spock's own passion for the same woman. Now this unimaginable conflict could cost Captain Kirk his very soul, and bring death to the proud Vulcan. But in the unimaginable lies their only chance, and the freedom of the galaxy depends on the outcome of the Triangle.
