I don't think I failed to grasp it... the reader knows what's going on and the real reason that he isn't there (which I didn't want to spoil in the review),

Wait... let...me...get...this...straight.... You're remarks about the bathroom thing being corny was doubtless one of the most scathing, seering parts of the review.
You mean... to tell
us... that you wrote that part...
because you didn't want to SPOIL anything?!?!?!?
You'll just have to read the book and judge for yourself... but the 'cover' for his absence was just so laughable...
in my opinion.
As for not spoiling, well, it's not a major spoiler, at least not in my opinion, and it's certainly not the final word on the situation.
Also, concerning the business of not reading the book and all, my intention is to write a review of the book, not to make buying decisions for the public. I realize my review may have some sway, and, if folks share a similar mindset with me concerning things, they'll probably have similar tastes. Heck, in my review of "Last Full Measure" I went so far as to point out that the novel was great, but proved once and for all that Enterprise wasn't genuine Star Trek.
I have no issue sharing frank opinions about my views on books, mainly because I want to see continued excellent storytelling in the Trek novels... if sharing my opinion helps, then so be it. If not, well, so be that too.
Every review, after posted, leaves you thinking about the things you might have been able to add, things perhaps you could have said, or things that you wish you wouldn't have. I really did enjoy the Trip storyline, and would have been pleased reading an entire novel on that alone. I just didn't care for the non-Trip portions of the book, and those in and of themselves really muddied the reading experience... again...
in my opinion.
Please, however, buy the book yourself and read it... you may or may not share my view, but hey, if we all agreed on our views, what would we have to discuss here?
