A Klingon is surgically altered to appear human in order to assassinate Kirk. He instead finds that humans are not the monsters he's told they are -- in fact, it seems that the Klingons making decisions are worse they say humans are -- and he has to decide what to do about it.

I noticed that on several occasions throughout this series that one Klingon character's name was substituted for another, as if the author (or maybe the editor) wasn't sure what to name these people. ( )
