This is the review to read.
This book is equally as excellent as Grone.
It is a mind-bending yet personal tale.
The world building leaves room for equally compelling tales from different characters' perspectives at different points in the timeline.
Instead of missing the characters from the last book, the next book becomes the favourite..
The main thing I want to get across is this is not best described as "For fans of Ready Player One" as I keep seeing.
These books have nothing in common other than they both have both physical and digital universes.
The Known Arc is a mature modern story which will become a classic.
RPO is neither of those things.
Instead, this book is for fans of: Protagonists with no special skills or birth-rights, Overcoming existential threats, Character driven narratives, Story driven narratives, Space Operas, Techno Thrillers, Quantum physics, Simulation theory, Ai, Qi, Fermi Paradox, and so on.
