Sometimes I get a little annoyed with books that tell the same scene from different perspectives, because I feel like they are just repeating stuff over and over. I didn't feel that way for Flipped, because it was really interesting to see the same scene, but one misinterpreting what the other is doing. And it is really great to see Juli falling out of love the same time Bryce is falling in love. It keeps you on your toes, like "Juli! Don't listen to that! He really likes you!" and things like that.
This is a really great book that I definitely recommend.
