Wow, I did not expect the direction this book would take. It was a very interesting read, and initially I thought it would be something mythological rather than arcane. The mix of journal entries and in-person events always pulled me further into the story. What I really like about Piranesi is that it doesn't provide all the answers and it leaves a bit of a mystery behind. What is the House, and how large is it? Are there other worlds? Who exactly are some of the people we meet? It simply doesn't give an exact answer, which I really like because not everything needs an answer. Sometimes the mystery is more appealing than the answer.
