Sorry for those who love this book, but this one just doesn't work out for me. The sudden change in narrative took a long while for me to really "be that character", because for some reason I cannot explain, all these characters sound the same. The metaphors and similes and whatever the author put in is too extravagant, and I know some people really love it, but for me, it doesn't really "flow" with the story. 
 Like some other people's reviews, I don't like the mom at all. She had another child because she just loved Katie so much, sooo much, and she treated Katie better than Anna, and she always have that exasperated look when Anna shown sign of opposing her and denying her. So instead of spending more time with Anna, she just stuck with Katie as if scaring the girl may drop dead in five seconds, and being angry and annoyed when Anna shown some sign that she didn't want to donate. 
 I just quit half way through the book, because the characters kept commenting on body's disease and blah blah blah, and people complimented Anna on her vocabulary, and stuff like that, and the mom goes crazy, and the dad try to console the mom. Whatever, I just go on Wikipedia and finish the summary for I am quite curious about the rest of the book. 
 After seeing Jodi Picoult's new book with her daughter "Between The Lines", my high expectation on this prolific author has somewhat curtailed.
