||I read this book over 20 years ago, when I was in college, but it was the one Star Trek novel that I kept (I had over 50). Yes, Spock goes back in time to foil a Klingon plot - but while you are reading the story, you'll (or at least I did) recognize several of the characters. The story is set in Seattle in the setting of the old TV show "Here Come the Brides". If you are old enough to remember that TV show, then you'll enjoy this book. Read the wikipedia entry for "Here Come the Brides" TV show from 1968-70. Some of the actors in HCtB were also on ST:TOS, and they are referred to in the book as "ancestors" of some TOS characters! Fun and original!
