Hello, I’m looking for a book about Napoleon that doesn’t make me feel like I’m getting a PhD. Ideally something well-written in the 3-400-page range.

Of course I can easily Google the best-reviewed biographies, but I’m not necessarily looking for a cradle-to-grave biography, and I’m not sure I’m interested enough for a thousand pages, so ideally it would be something that splits the difference between a Wikipedia page and Andrew Roberts – and please notice that I’m looking for a book, not necessarily a biography, so take as much leeway as you want. Any and all suggestions appreciated! Up-to-date would be good but not essential; older historians can have interesting takes and I can apply my own salt.
