Star Trek book question?

[JimPghPA]

I want to recommend a Star Trek book to someone but I can not remember the name of the book. It is the one written about Spock having a son from the episode where he and Mcoy and Kirk went back in time and met a lonely woman living in a cave.

Does anyone know the name of that book?

All our Yesterdays was the episode. Mr. Atok was the librarian.
I think the sequel book Yesterday's Son is what you seek.

Thanks for the replies.

Mariette Hartley was the woman trapped in time (but I loved what she did to her cave) and Ian Wolfe was Mr. Atoz, the librarian. A to Z.

Ironically, they're showing All Our Yesterdays on BBC America right now.
Mariette Hartley is a complete dish.
Yep, Spock and Zarabeth did it in the cave.
