Jonathan Strange and Mr. Norrell by Susanna Clark. I am finding this challenge tougher than I expected.
The first difficulty I am having is finding books that I want to read that are 700 pages or longer. When I signed on I had several books in mind that I want to read, but closer examination revealed that most of them are not that long (500-650 pages mostly).
The other problem I am having is that it takes so long to read a long book (obviously not something I am in the habit of doing) that I keep wanting to pick up and read other things that draw my attention. This is OK, except that I have limited time to read (that job thing takes up a lot of time) and finishing the long books gets tougher the more other books I have going.
Of course, if it was meant to be easy, it wouldn't be called a "challenge" so I will press on. I did decide to enlist the law of averages to fit in one of the books that inspired me to take this on into the challenge. I finished 1Q84 (925 pages) and Jonathan Strange and Mr. Norrell (846 pages), which is 371 pages beyond the required 700 per book. I am applying that "credit" to The Historian by Elizabeth Kostova (at 642 pages) and making it one of my 6 long books.
