** spoiler alert ** 
 I really liked this book, and loved the character progression. I was so proud of Hanna at the end of this book (just like I was with her in the book that came before this one) and how she realized that by stalking Colleen, and trying to break her up with Mike, that she was becoming a version of A. So she stopped, and "beat A at her own game". Besides, she got Mike back in the end, once he realized how much she really does like him. So she got a happy ending.....for now. 
 Spencer........ I'm glad she realized she didn't need to be in an eating club, and I really hope that in the next book she gets to know Reefer better. 
 I liked Aria's storyline, and am glad that A only ruined it for a second, before Noel brought her to her senses. 
 I felt extremely bad for Emily in this installment. Not only do we see the return of Gayle, the woman she originally was going to give her baby up to, but she has to deal with the return of Isaac (the baby daddy) and whether or not she should tell him, along with her constant worrying about her baby, because the adoptive family has moved away. At the end, she tells Isaac, Gayle is killed, and she finds her baby is safe. Now, in the next book, I hope she FINALLY tells her parents tha she was pregnant last year. 
 On the subject of A.....whenever the girls point the finger at someone, you automatically know it's not going to be them. It's interesting to in the end how their theory is blown out of the water though. In this one, Gayle ends up being found dead (much like previous A suspects before her Alison ((well, Courtney's dead body, but everyone thought she was Ali)), Toby, Ian, and Jenna) 
 I can not wait for the conclusion in the series, and how everything will be tied together!
