This looks slick! I've not been tempted by any of the higher priced "show off" iPad apps, but this one looks like I might enjoy it more than just simply to "see what it can do". I'm intrigued by the idea of features that unlock as you read them, instead of having to save them until after you've finished the entire book.
I have a paperback copy of Pillars of the Earth and an epub of World Without End. It's been a while since I read the original -- I went into it knowing nothing except that it was a bestseller and whatever the blurb on the cover said. I was in a book buying mood and I was looking for something with a long and involved story. As I was reading, I was surprised at how much I enjoyed it. I've been wanting to read it again since learning about the mini-series even though I have not finished reading the sequel. (I am having a hard time "getting into" it.
Not sure why, but I recently gave up again.)
