I DID, yes!

It's a lovely book, beautifully written with a fantastic, innocent/amnesiac, main character.

Now you need to try immersing yourself in 'Jonathan Strange & Mr. Norrell' by the same author.

OR, try 'The Starless Sea' by Erin Morgenstern (who also wrote 'The Night Circus'), which is a decent length novel but not a massive one, and has a lot of similarities with 'Piranesi' - so much so that I sent a copy to Reece, and you know how he is about fantastical storylines!
