Coincidentally, I just finished this book last night! Overall, I found it enjoyable. More so than 1 1/2 of the previous numbered books. In spite of some "problems" (for want of a better word which if I had, I could write my own books!).
What I never really figured out was the meaning of the title. I must've drifted off to sleep when the connection was made. It also had the feel of a Wild, Wild West TV Show episode, in that hero a/b/c was in trouble when the commercials started, only to be rescued/solved in the first 10 seconds of the next act.
Oddly, enough I'm enjoying the DS9 books overall, much more than I did TOS books over the decades. But that might be a side effect of the decades that have passed, or a lower expectation? Perhaps I've learned to ignore the fact that every single Trek book I've read over the past 40 or so years, has had at least one major problem or mischaracterization or whatnot. No matter, I am enjoying them overall.
