Mr. Penumbra's 24 Hour Bookstore

Mr. Penumbra's 24-Hour Bookstore by Robin Sloan

I loved this book....as much as I loved another bookstore book, The Storied Life of AJ Fikry.  In this book, Mr. Penumbra, like the title says, owns a 24-hour bookstore.  Clay is the night clerk at the store and realizes that this is no ordinary bookstore.  While popular titles are sold in the store, the mainstay of customers want the "back shelves"....books that seem to be full of puzzles and are not purchased, but borrowed and then returned.  Clay begins to investigate and realizes that there is a secret society within the clientele of the book store and that they are trying to decode a message from centuries ago.  Written well with a mix of past and present (Google plays a large role), this book is a perfect blend of mystery and fantasy.  Sloan has created interesting characters and a wonderful setting in the bookstore.  I highly recommend this read.
