The first part of the book was a slog for me, and I kept putting it down, but once a few levels of awareness for some of the characters really set in, it was a great read. Many plot twists. I especially enjoyed the end sections. Meta on meta. Wonderful.
After reading a several reviews, in particular one by my favorite author Patrick Rothfuss, I decided to step out on my normal reads and give this a go. The reviews indicated that I would laugh aloud as opposed to just "lol'ing." They were not wrong. I laughed in the first pages harder than expected. I enjoyed the book so much that I bought the audio just to hear a talented orator put inflection on some of it. Aside from the laughs, it had a nostalgic element from my times aboard the Enterprise. A very original feel to the book and the story.
SPOILER: No plot details here, I am going to give away a major theme that you might want to figure out on your own. Can't help that.
Red Shirts is a novelty more than a novel. It is about "popping" the system, meaning the characters keep reaching up to the next level of reality. That is the characters figure out they are really actors in a movie.
This is kind of interesting, but it gets old, and it really weakens the story. By the end, there is not story, just this meta-story, about stories in stories in stories like a Russian doll.
