The Great Recession has shuffled Clay Jannon away from life as a San Francisco web-design drone and into the aisles of Mr. Penumbra’s 24-Hour Bookstore. But after a few days on the job, Clay discovers that the store is more curious than either its name or its gnomic owner might suggest. The bookstore’s secrets extend far beyond its walls. -Goodreads
