Spoilers? Isn't this the first Trek novel ever published or something?
Well, there may be people out there who have only read the books of the last 20 years, compared to a book that is 40 years old, or they are just starting to read Trek.
Even though I have been reading Trek literature on-and-off (mostly on) since, well, Christmas of 1991, I only read Spock Must Die!
last week. Especially since it doesn't seem to have anything to do with the currently continuity, and is a bit obscure, there's room for surprises.
