29 year old Clay takes the graveyard shift at a mysterious 24 hour bookstore after losing his marketing job with a bagel firm. Soon he realizes the few customers that visit the bookstore are actually part of a much larger organization revolving around a secret order and trying to decipher some sort of code.

If you enjoyed "Ready Player One" which I thoroughly did, this is another enjoyable geeky read for 30 somethings. Lots of likeable characters, humor and fun. Great audiobook with a great narrator.
