Time for Yesterday (Yesterday Saga, 2) Star Trek Paperback Book. This Star Trek adventure was published in April 1988. Time for Yesterday (Yesterday Saga, 2) was authored by A. C. Crispin. Rest assured that this vintage paperback book may show signs of wear. Still, the copy you receive will be in excellent or better condition than the one in the image. I have multiple copies of each book and make every effort to represent the actual book accurately. You can trust that I stand behind my products with a no-questions-asked return policy.

Here is what is on the back cover. Time in the galaxy has stopped running in its normal course. That can mean only one thing – the Guardian of Forever is malfunctioning. To save the universe, Starfleet Command reunites three of its most legendary figures – Admiral James T. Kirk, Spock of Vulcan, and Dr. Leonard McCoy – and sends them on a desperate mission to contact the Guardian, a journey that ultimately takes them 5,000 years into the past. They must find Spock's son Zar once again, and bring him back to their time to telepathically communicate with the Guardian.
But Zar is enmeshed in troubles of his own, and soon Kirk, Spock, and McCoy find themselves in a desperate struggle to save both his and their world. Give GoFigment a chance. As a dedicated Star Trek collector, I only sell items that meet my personal collection standards.
