Mr. Penumbra's 24-Hour Bookstore - Softcover

Amazon Best Books of the Month, October 2012 (Debut Spotlight): Mr. Penumbra's 24-Hour Bookstore is an old school mystery set firmly in tech-loving, modern day San Francisco. Clay Jannon (former web designer) lands a job at a bookstore with very few patrons and even fewer purchases. His curiosity leads him to the discovery of a larger conspiracy at play, one exciting enough to rope in his best friend (CEO at a startup) and love interest (works at Google). As Clay and company unravel the puzzles of Mr. Penumbra's book shop, the story turns into a sort of nerdy heist, with real-life gadgets, secret societies, and a lot of things to say about the past, present, and future of reading. Sloan originally self-published Mr. Penumbra as a short story through Kindle Direct Publishing, before expanding it to its current form with a traditional print publisher--a fitting trajectory for a fast, fun story that has so wholly and enthusiastically embraced the tension between the digital and analog books. --Kevin Nguyen
