As a video game adaptation, it is not the greatest book, but for the fans of the game, it makes a good summary of the story and established a canon of events (something complicated with so many endings).

It also focuses a lot on the thoughts of the characters and motivations, and also explains some of the most confusing parts of the ending (greatly appreciated).

As engineer, I also found very funny how accurately pods behave like a kubernetes cluster.

If you are a fan of the saga, this could be perfectly a 4-5 stars book because it completes and clarifies the game. If you come with no knowledge, it is a 2-3: entertaining, but not great.
