The most challenging thing about this book is how many times you're going to be turning the page. But along the way, the prose is totally readable and mostly plot-driven. Yes, you're going to face some huge digressions where Hugo walks away from his plot for 10 to 15 chapters at a time. But stick with him and he'll always bring you back to the action.
