I liked this book more than the first one. Although the first half consists solely on Juliette and Adam whining, the second half brings Warner in, and with Warner comes a different more real Juliette. Even though there still more romance, at least there is a little more plot in the story. 
 I think Juliette talked more to Warner in a few chapters than the whole of her dialogs summed up of book 1 and first half of book 2. Warner makes Juliette feel comfortable with herself, and you actually notice when she makes "the click" and start behaving more like herself, less insane and dependent and afraid of everything. Her character development is really good. 
 Regarding Warner, I'm in love with him. By far the best character in the series, you get to know him better in this book and just want to jump into the story and hug him. 
 Adam still has no hope... he's still boring.
