7. The Sherlockian

The Sherlockian, by Graham Moore, mixes modernity and antiquity in mysterious ways. The cover is superb. The story is interesting. I've got my qualms with how the character of Arthur Conan Doyle was handled, but all in all, it's a game of dual detectives that leads you down trails of parallel meta mysteries. If you're wondering about that video interview with the author I mentioned, you can find it here.
