And it's time to 'publish' another! "A Piece of Forever" is the sequel to, obviously, "The City on the Edge of Forever," but in this story, Kirk and his handful of Enterprise
officers were unable to return to their own time. With their knowledge of the future, their personal experience and knowledge of the technology of their ship, and recordings that Spock is able to recover of the decades ahead, they work in secret to find a way back into space, and back to the Guardian.
