Query: Jonathan Strange and Mr Morrell

A first indicator of what you're going to experience in this book is the fact that the introduction is by Neil Gaiman. If you know of and like his work, this is your book ... although it is quite, quite different from much of what Mr. Gaiman does.With over 700 other customer reviews, I don't want to go into a lot of details about my personal experience with this work. I just want to record for the ages that I think this book is utterly entrancing in a slightly creepy way. It's a bent and dark world of astonishing characters and relationships and plots. It's not for your average fantasy reader at all, though. Whoever you are, be ready for something that might be unlike anything you've read in years.
