As far as I know this was Sonni Cooper's only shot at a Star Trek novel. I'm 40 pages in and the dialogue screams "amateur hour" but it's pretty short so I'll see it through.
No, I'm sorry to say this is in the running for the worst Star Trek book I have every read. The dialogue trots out every cliche known to mankind. I had to stop when Kirk goes to make a log and gets the message "If you're reading this, then I am probably dead."
NOPE, NOPE, NOPE. I am currently rereading all of the pocket books in no particular order and I have been able to plow through anything from Carey to Culbreath/Marshak. The quality of this book is so far below the typical Pocket standard that I can't fathom how this book was ever published.
