I was made aware of this book by another book (shocking, I know). The second book is called A View from the Cheap Seats, and it’s a compilation of speeches and essays and articles by Neil Gaiman (whom I quite admire, as you may now have guessed). It’s also an excellent read, and I would recommend to any reader to pick that one up, too. Anyway, Jonathan Strange and Mr Norrell is quite an extraordinary work. Do be aware, it’s a bit of an undertaking (kind of like what a tree removal service might have to go through in some particularly foresty yards, except much more enjoyable, I imagine), compared to some of the others I’ve mentioned here; the version I bought consisted of a little over 1000 pages. It’s totally worth it, but just be aware of the length!
You may be thinking that the title Stardust sounds familiar, but that you don’t remember reading it. That’s probably either because you have a friend who is an avid reader and has raved about it to you (because he or she, correctly, has likely insisted that you read it), or because you have either seen or heard of the movie. With Claire Danes, Robert De Niro, Michelle Pfeiffer, Ian McKellan, and Ricky Gervais involved, it was a pretty star-studded flick (and, for the record, the main character was played by little-known Charlie Cox). And the movie was lovely. It was a long time in the making and Neil Gaiman had a very large part in its creation, which likely had lots to do with its quality (just like, I imagine, the work of roofing contractors would be better if the designer of the house were there to oversee it).
