suuuuper fun! 
 this book is going to sell like gangbusters when it comes out in october. mostly because each and every one of you reading this review are going out and getting yourselves a copy. this is a command. 
 you like books, right? yes, you do, because you are a member of goodreads. and this book is about books! and puzzles! and adventure! there's not a whole lot that's better than that.it is shades of Salamander and The Grand Complication: A Novel and If on a Winter's Night a Traveler and The Name of the Rose, but it is definitely distinctly its own. 
 this book is just a pure joy to read - each character has their own particular skill set, and are quirky without being cutesy about it, and each contributes to solve one hell of a book-mystery involving secret booknerd societies, typography, ancient artifacts, codes and puzzles, the capabilities of computers,and the coolest bookstore you have ever heard of.the mystery is satisfying and the attention to detail is very much appreciated, plus i learned a thing or two. 
 this is one of those books it is better if you discover and experience on your own, so i am not going to say anything else about it, suckers! 
 but this is wild, page-turning fun, and i urge you all to get your hands on a copy if you like books about books. and you do.
