Ringer

I was looking for a quick sci-fi read as a palate cleanser between fantasy tomes when Ringer made a timely appearance on my Twitter feed.
Ringer is a short, entertaining and slightly predictable read (which is not always a bad thing, especially when all you want is to enjoy a character's journey through an existential dilemma), carefully written to induce wonder, suspicion and even paranoia. I particularly liked how thought provoking it was at times and, if anything, I wish it had delved a bit deeper into the psychological and social implications of the plot.
