Unfortunately, I didn't care as much for the book as I was hoping. A lot of it is really interesting, but a lot of it is extraordinarily dry and humorless also. Some of it is even tedious, and I was wondering if it could have had a stronger editor. I thought the descriptions of the "Mirror World" were excellent, and I would be really interested in reading further information about those strange corridors--like who is the person that Mr. Norrell noticed in them? 
 Anyway, I wouldn't recommend this book, but I wouldn't stop someone from reading it either. Maybe they'll enjoy it more, but for me, it isn't as interesting as it looks.
