This may have had the most characters included in any book I’ve ever read. It was a little hard to keep track of everyone, but I loved the full cast of narrators for the audio book. I also loved that each character came with a voice and writing style that was unique to their personality. This is quite the interesting concept of uploading your memories to the collective. Honestly, I could go back and read this again to try and decipher who all was connected to who.
