Okay, the user wants a book description that hooks and tells the ideal reader. Let me parse the book details. Genres: History. Moods: dark, informative. Slow-paced. The description mentions paranormal events influencing political events. It explores the paranormal's influence on various aspects like law, government, military. So the ideal reader is someone interested in the intersection of history and the paranormal. Need to phrase this in a way that's general but descriptive. Avoid specific terms like presidents or Houdini. Think about readers who enjoy unconventional history angles. Maybe phrase it as history enthusiasts with a taste for the supernatural. But be concise. Let me structure it in one sentence.
