Permafrost

This is a time travel story with a lot of imagination. I liked the explanations AR gave to the theories on it, and that he did not mess a lot with them. The seeds, the role of the AI, time-embedding, the noise in time and the interjection between minds are a few of the themes in the book and quite a different approach from other stories of this kind. I would have prefered the book to be a bit longer as the last 3rd of the book felt rushed. Also, I did not like the ending , it was not interesting at all. Or maybe it's just that I wasn't expecting to end too fast and took me by surprise (in a bad way).
