Hats off to John Scalzi and Audible for this great near-future sci-fi. As with all good sci-fi, there’s an implicit social commentary built into the way the future world is shaped, and Lock In is no different. What if millions of people are suddenly unable to respond to external stimuli but are fully conscious? What sort of a world do we create or do they create? What are the prejudices we bring with us into that world? 

All well and good. And also a great detective novel. 

Another interesting thing, there are two narrations available (I think you get both when you buy either) one by a male narrator and one by a female. What does it say about me that I listened to the male version first? Maybe that I have a mancrush on Wil Wheaton? IDK.
