This book (and the rest of the series) is genuinely the most phenomenal listening experience I have ever had. The narration is what truly makes this series and whenever I recommend it I tell people the audiobook is a must (at least first read!) There are compelling characters, plot lines and system dynamics and the story may seem purely silly at first with the crazy achievements and the system A.I breathing heavily into your ear but by the time you are too entangled to leave the begin touching on the depths of the human (and alien) soul. I genuinely have not been hooked on a series like this since I read Percy Jackson at 11! I can not recommend this book enough.
