An okay early entry in the Star Trek novel series, The Klingon Gambit just doesn't have the flair and action of the best adventures of the Enterprise. There's also a lot of out-of-character actions by the crew (for reasons that will become obvious), especially Mr. Spock. A lot of these books try to explore the Vulcan-Human dichotomy within the character, and end up trying to bring out his emotions in ways never evidences on the original series. In a few instances (like The Vulcan Academy Murders it is limited enough to work and even be a boon to the story. In this story, it's more annoying than anything else.
