This book starts as just a fun romp with a somewhat nonsensical time travel experiment and slowly evolves to a much darker and more reflective tone. This shift was unexpected but not necessarily unwelcome. I struggled with the writing style at times but those struggles were easy to push through and did not take much enjoyment away from my experience. As with any time travel story it never quite makes 100% sense, I do wish the technicalities of the time travel were explored a bit more. I think further explanation and emphasis on this would only aid in creating the sense of importance/urgency that was building up in the last third of the book. I wanted more fun romp and less exploration of the flaws in our society. The flaws were explored quite well, I just didn't know that's what I was getting into.
