One of the best sequels in a trilogy that I've read. It may not be much in the way of progressing the main love story, but goddamn does it drop all these awesomely gasp-worthy little tidbits. What I love about this book is that I really couldn't predict a single thing (other than the love bit...pretty standard soap opera drama/forced amnesia deal.
And Ruby makes up for all her little weak moments, and even her giant weak moments from the first book (which is the most important thing).
Also, Cole. I ain't takin' hate from no one about this. He is awesome, hilarious, and cooler than Lee. Suck it. Also he is my age, which makes me feel better about reading teen books.
