Lemme just say one thing first - Omg omg friggin finally and oh so sweet.
I absolutely loved the conclusion to the trilogy.
Loved the plot and her and Jack. That just made my day. I'm glad to see Quinn go. He was a pain, what he said just screamed condescending ass to me. But it was nice to see, so I wasn't wrong in thinking there's something wrong with him, nobody is that perfect.(show spoiler)
And Jack - he was just awesome. More talkative this book, so I got more of a feel for him and I liked what I saw. I think they're well suited to each other.
