I thought this book was good! With Mona gone Aria, Emily, Hanna, and Spencer can continue their lifes without having to worry about "A", right? Wrong. There's a new "A" in town, and they plan on messing these girls up just like the original one did. But there's something different about this "A". Sure, she/he's kept remindind them of their deepest darkest secrets. Sure, she/he's terrorizing them about new secrets their making. But it seems like "A" is also doing something else, helping them figure out who really killed Alison. And the truth is shocking! I would recommend this book to anyone who likes saucy stories that are realistic, yet in a way mystery books. Since this quailifies as a book for young adults, I woulnd't suggest anyone under the age of 13 to read it.
