Lock In
by John Scalzi

My rating: 4.5 / 5
Genre: Sci-Fi mystery

In the near future, a disease ravages humanity, leaving a large population of Earth completely paralyzed. In the time period of Lock In, technology has been developed to allow those “locked in” to live as normally as possible, either putting their consciousness into a robotic being, or into the mind of someone who has the ability to accept the mind of someone else. Set against this backdrop, the book is a mystery that starts with a murder, but deepens continually as the story goes on.

I wasn’t really expecting to like this book that much, though I don’t know why. However, I ended up liking it a lot. The sci-fi element, mainly the roles the Hadens (those who were locked in) and the Integrators (those who could let a Haden use their mind & body) played in the mystery, really enhanced the mystery plot.

The main character, Chris Shane, is a Haden and an FBI agent, who interacts with the physical world in what they call a “threep” (basically a robot that is controlled by a Haden’s consciousness). In a lot of ways, the book was similar in this area to Ready Player One, which I only read recently, so it was fresh in my mind. I was interested reading about the laws surrounding Hadens and their threeps, when it comes to crimes committed both by and against them. I also enjoyed the main character’s intelligence, ingenuity, and stoicism.

Another thing that I found myself appreciating throughout the book was the writing style. There is not a lot of description or figurative language, which to my taste, at least, can slow a story down or add unnecessary filler. There were even times that I would read through an entire page and get this feeling in the back of my mind that I’d skipped some text (I do that sometimes, essentially accidentally skimming for a bit before deciding I need to go back), but when I’d go back to try to find what I’d skipped over, there was nothing. Conversations flowed quickly, with little in the way of descriptions of what the characters were doing. Some may find this a flaw, but I personally liked it. If the characters aren’t really doing anything but sitting and talking…maybe sometimes it’s okay to not add minor actions in just because. I usually write dialog this way too, but end up going back and adding more in, because I feel like it’s expected.

Scalzi’s world-building was brilliant too, from following the progression of politics, laws, and citizen response brought on by Haden’s syndrome in America, to the slang and lingo that seemed so natural in this world. My main detraction in the book is involved in this area though. At one point in the last quarter of the book, a side character who is an expert in a field that is needed for the investigation spends about 10 pages explaining some technological and coding mumbo jumbo that I had a difficult time wading through and understanding. I was at least able to come away with some idea of what was going on, though, so it didn’t cause enough problem for me to be more than a short frustration. I also feel it prudent to mention that there was a lot more language than I prefer.

I had seen that there is a follow-up to this novel when I wasn’t even halfway into reading it yet, and I didn’t expect to have much desire to read it. However, by the end of the book, I knew I had to read Head On at some point soon!

I would recommend Lock In for fans of near-future sci-fi and for mystery lovers too.
