The book explores the idea of simulation theory and posits (I feel) some subsequent questions and alternate interpretations that were interesting to explore and think about. Some of which I had not thought about until the author presented them. There is a religious element however 1) it’s not preachy, it’s the character struggling with his own beliefs and is enough to incorporate the religious perspective without it dominating or controlling the narrative of the overall story. the author isn’t trying to convert anyone and it doesn’t come off that way to me. overall it’s a good book and i enjoyed it. it starts off a little slow but by the time i hit the middle I was listening to it whenever i got the chance. that carried through to the end. I would reccomend.
