"Moved me close to tears" is not something you would normally write about a Star Trek book, but A. C. Crispin's Yesterday's Son had me reaching for the tissues by the last page.
When Spock realizes that he left behind a son on the planet Sarpedion (see the 3rd season episode All Our Yesterdays, TOS), he uses the Guardion of Forever (see 1st season episodeThe City on the Edge of Forever, TOS ) to retrieve him. Only by the time they find the boy, Zar, he is 28, too old to be easily explained as Spock's son. As the newly-formed family struggles to bond, a Romulan attack threatens the Guardian - and the galaxy as the crew knows it.
This was A. C. Crispin's first novel and it is an impressive debut. Strong writing, good characterizations, and a heartbreaking family drama sets this short novel above the rest. Highly recommended.
