Sea of Tranquility

I found this touching and hopeful, I liked how poignantly the characters were drawn, and the themes of kindness and the vicissitudes of life.

My main complaint was that I think the simulation theory stuff was basically an unnecessary macguffin and didn't add to the themes (at least as far as they interested me).

Fantastic to a point I did not expect. Very meta, and covers aspects that took me by surprise. I rarely read the descriptions of books written by authors that I have read before, and here it totally paid off. If you have read the previous two works by this author, you will like where this book takes you.
