Wonderfully Intruiging!

I have read a first extract of this book. First impressions are great, the cover invokes mythological history which I love. It seems intruigingly complex and is very descriptive- I feel that I should be making notes as the main character Piranesi does!
It is giving me vibes of The Starless Sea with endless halls, stairs and rising seas.
I really want to read on and see how this one develops.
