I didn't like that every time a new character was introduced they were given chapters dedicated to their own issues. It took away too much attention from who I believe was intended to be the main character and didn't allow me to delve into her storyline as much as was needed to allow me to create emotional attachments to her. Delving into the vast amount of other characters lives was overwhelming and left a confusion as to who actually was the main character as the story progressed.
However, I did find it easy to read and I did love the ideas behind the different character plotlines, I just feel they would have made very good separate books where we could explore each life a bit more, rather than trying to jam it all in one book.
