[These notes were made in 1983:]. Altogether one of the best ST novels I've read. Literate, with a good grasp of plot development & characterization, it deals with Spock & emotion without going goo-goo-eyed over the whole thing. The plot is directly based on the "Library" episode, Spock's prehistoric inamorata being supposed to have borne him a son (a very unVulcan one, except for the ears). A trip back thru' time retrieves this son, long enough for him to help in a campaign against the Romulans, before he realizes his destiny is in the past and returns, leaving the ST universe conveniently unruffled. A nice little heartwarmer - I hope she writes more.
