Mr. Penumbra's 24-Hour Bookstore (2012)
Picked up on a whim due to the fact that the word 'bookstore' was in the title, and not knowing anything prior about the story itself— I was pleasantly surprised with this read. In fact, this is probably one of the best fiction reads I've read in my lifetime. Although it took me close to a month to finish it, I enjoyed every word on every page of Mr. Penumbra's 24-Hour Bookstore. The Da Vinci Code meets National Treasure is one way to describe the story line of this book. Upon finishing reading this work I immediately searched to see if there was a sequel, prequel, or even a movie based upon it. No dice.
This book is an easy keeper, re-read, and recommend.
