Ohmigod, I actually thought this series would last forever and it didn't! YAY! I loved loved loved the ending. In looking back, the only books you need to read are the first and last and you'll be fine. Actually, if you want the most action and closure, just read this one. Or the halfway point book in the middle where they find out who the original 'A' is. I can't remember which book that was, but it was good to. Definitely on par with this one. I think I liked these best because stuff actually happens and there is an actual ending. I need closure! This story is wild, goes off onto tangents that are pretty unbelievable, but I still loved them all the same. And the girls actually were together for most of the book, which I liked a lot. And YAY for a crazy ending (or was it? Who cares!!). Just all around nuts. If you like YA, pick this and only this book up. Thank me later.
