** spoiler alert ** 
 o.m.g! this book is an excellent book. I could not put it down! I related so much to Katie throught most of the book. There were only two things I did not like about the the writing. The first that it would constently jump back and forth between Katie and Tully in terms of story and I know it made for a better story but sometimes it was really hard to follow. The second thing I did not like was the end. I mean come on! the nice girl gets cancer?! Really!.? It really made mad that Tully stays alive and her "friend" dies? To me thats screwed up. It should have been Tully that dies. Karma for bieng such a bitch to Katie (and Johnny and Chad).
