It's been years since I picked up a nonfiction book, let alone finish one. But I enjoyed the Nihon series so much, I am starting to love reading again. Some of the things I imagine to see is the clash between Nihon and the Other Side, or if there's a possibility of Sofia being able to recreate a copy of herself who has an independent but basically similar mind to her. Your story gives so much room for the imagination — I love it! I hope you continue the series, but do take your time.
