I received a free copy of this book in exchange for an honest review.
This is an intriguing cross-genre mix: part prison story, part mystery, part horror, part psychological thriller with a dollop of invasion of the body snatchers.
It took a little while to get used to the writing style, as it seemed very confusing at first - until I realised that that was the point. For the first third or so of the book, the trick is figuring out what's real, what's hallucination and what's virtual reality, underpinned by the question of what actually happened to the Helena Isaacson, whose murder the PoV character is imprisoned for.
Once we start being introduced to the underlying story, it gets closer to more standard SF, with a different take on a worldwide conspiracy theory. The author has come up with some interesting ideas, including a slightly version of uploading consciousness, and the possible reasons for doing it (although I'll admit I'm not entirely sure the 'science' of it is convincing).
All in all, I liked the book (three out of four stars on my personal ranking system), which seems to offer an original take on various themes, and ultimately this leads to a discussion of what really makes 'self', and whether people are ever justified in doing bad things for good reasons.
