The Folded World & The Shocks of Adversity,
This review is from: Star Trek: The Original Series: The Shocks of Adversity (Kindle Edition)
The two titles I've used here are the exact same story by supposedly different authors - the synopses are even the same.
Both mention the science vessel McRaven, both plots are the same, the exact same words in the exact same order are in both books.
If you've read one then you've read both!
This is not just plagiarism!!
