Query: Disappointing

After seeing this book prominantly displayed in my local bookstore time after time, I finally bought it. I was excited at first, but my excitement quickly faded as I muddled my way through the book. I kept hoping that the book would get better, but it didn't. I agree with another reviewer that there isn't enough character development here, even with Jane. She comes off very shallow, and she's not someone I would really care to know.Another mysterious section is one of the stories in the middle of the book. The narrator is Nina, not Jane, and it doesn't really fit anywhere in the book, except she is the downstars neighbor of Jane's much older boyfriend. I kept waiting for any of the characters in that section to reappear, but they never do. Something funny does happen in that section, but you never know what the resolution is.The best part of the book is the last section where she tries to live by the oft-mocked Rules. I wish more of the book was like the last section!
