I thoroughly enjoyed this book. Not only does it give you a thrilling story line but it leaves you constantly thinking about the possibilities of the world. I remember being in science lessons learning about gene-editing and DNA and why it thought of badly and this book gives a well rounded look at all the possibilities that could happen because of the advancements. It is amazing to think of a world where people can get a permanent tan or extra muscle through a bit of scientific work and it almost seems idyllic. Then you hear about the viruses that can be cause and the billions of people dying and it leaves you wondering which world is better. It's crazy that you could even think of that world being better but somehow the book leaves you wanting to be there. I often struggled to tell what was truth or fake. We are so close to a world where that is all possible and though technological advancements are amazing in some cases, it's good to think and discuss the possible negative side affects. Genuinely in awe over this book. I have found myself talking about it so much and I think I will do forever more. Truly thought provoking.
