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

"This odd, delightful book by Robin Sloan is about what happens when medieval mysteries meet modern technology," writes reader Carol.  "The story follows a clerk recently hired at the eponymous store as he tries to solve the riddle of Mr. Penumbra's very odd collection of books.  Ultimately, technology and secrets are both the richer for meeting each other-and as the reader, I'm sure I benefited most of all."
