I really enjoyed this book.  Each chapter was from the point-of-view of a different character in the book so you really came to kow the characters well and understand their motivations.  There was no good guy or bad guy to root for, just characters with decisions tomake with no clear right and wrong--very thought provoking and enjoyable at the same time.  It wasn't predictable in the least. 

I absolutely agree with you.  I read this book a few months back and absolutely loved it.  I thought Jodi Piccoult's writing style was very exciting and caused me to quickly get into the characters of the book.  I found myself not being able to wait until I got to a particular character depending on the topic because I wanted to read the characters view.  I also agree with you that this book was anything but predictable.  I am really looking forward to reading her other book, Nineteen Minutes.  I have it but haven't gotten to it yet.  So many books...
