How far are you? Are you reading all of the footnotes? I am so confused about it all but I love it. It has really sparked a curiosity I haven't had in awhile.

Btw, have you heard of the book Ship of Theseus? I bought it for my wife and we haven't jumped into it yet but seems similar in that it's a big puzzle: https://www.amazon.com/Ship-Theseus-J-Abrams/dp/0316201642 (and JJ Abrams if you're a fan)

It amazes me that they could make it in bulk for $20 (https://www.amazon.com/Ship-Theseus-J-Abrams/dp/0316201642).

Among the pages are cards and other items that the two fictional readers shared or saved.
