Vulcan's Glory (novel)

Summary
From the back cover: Here is a very special Star Trek novel - from the woman constantly voted by the fans as their favorite writer from the original Star Trek television series!

D.C. Fontana, writer of such classic Star Trek episodes as "Journey to Babel" and "This Side of Paradise", here brings us the never-before-told story of a very young Mr. Spock, on his first mission aboard the USS Enterprise. You'll also meet Captain Christopher Pike and his enigmatic first officer "Number One" (previously seen only in the original Star Trek pilot, "The Cage"), as well as the ship's brand new engineering officer, Montgomery Scott.

Vulcan's Glory is the tale of Spock's struggle to reconcile his many obligations - those forced on him by his Vulcan heritage, and those chosen by him upon his enlistment in Starfleet - to balance the wishes of others against the desires of his own heart.
