Everything--EVERYTHING--in this book is gold. I finished it a month ago, and I'm still having feels; it's that good. And to be honest, it is by far the best sequel I have ever read, which is not something I take lightly. Everything in this book is as fresh and new as it was in the first, and I couldn't put it down. Literally. I read it in six hours.
Moral of the story: read this series if you do nothing else.
