The Book was "Ishmael" by Barbara Hambly. "The 'Enterprise' is on a peaceful mission at Starbase 12 when a bizarre cosmic phenomenon causes a Klingon ship to suddenly vanish--with Spock aboard for the ride. Spock's last message from the Klingon ship is cryptic and frightening. The Klingons are traveling to the past, searching for the one man who holds vital key to the future. If they can kill that man, the course of history will be changed-- and the Federation will be destroyed." Contains references to "Here come the Brides" and major characters from the first season including the Bolt Brothers, Candy Pruitt, Biddy Cloom, Aaron Stemple, Lottie Hatfield and Capt. Clancey.
