I was told beforehand that there is a plot twist at the end and I was giving my best to figure it out with each read chapter (or should I say "diary entry"?). I'm a bit disappointed to say that it was pretty predictable for my (pretty high, I will not lie) expectations. Despite that, my god, this book was magnificent! It made me live in Piranesi's world and see it clearly through his eyes. Solely based on that I can happily say that it's gonna become one of my favorites and I will be re-reading it soon. Absolute magic! I want to go back to this world, too.
