Query: style is most frustrating

I notice that a lot of people really like this book, but I found it very irritating. It takes until page 386 before the author gets to the point. In the meantime she uses and re-uses a couple of really irritating devices: characters constantly repeating factual information, like the symptoms of various diseases or constantly going over their concerns about someone's welfare; or character's about to find out some crucial piece of information but constantly being frustrated by some minor mishap. I get enough of this kind of thing every day at work and don't need to read it time after time in a book. The basic idea of this book is good and the last quarter of it moves along at a reasonably good pace. But it takes a long time to get there and I almost put it down several times.
