From the back cover: Four pretty little liars' charmed lives have turned into living nightmares. Emily's been shipped off to Iowa to live with her überconservative cousins. Aria's boyfriend is behind bars—because of her. Spencer's afraid she was involved in Ali's murder. But Hanna's fate is far worse: She's clinging to life in the hospital because she knew too much. If these girls don't start listening to me, Hanna's ging to look like the lucky one. ~A

First sentence: Ever wish you could go back in time and undo your mistakes?

My review: Unbelievable picks up where Perfect left off: moments after Hanna's accident. While her friends and family pace the hospital's waiting room to learn Hanna's fate, "A" continues to threaten each girl. Emily is sent to live with her cousins after her parents learn she kissed the new girl, Maya. Little does Emily (or her parents) know that her cousins aren't so innocent and have issues of their own. Meanwhile, Aria is trying to cope with her parents' imminent divorce. Just recently broken up with her boyfriend, Sean, Aria has no place to live. She's forced into moving in with her father and his mistress and isn't thrilled to hear their latest news. Spencer is up for the Golden Orchid award. . . something she has always dreamed about. The only problem is she plagiarized her sister's paper. When she learns she made the finals, will she come clean and confession or will "A" out her? Hanna is in the hospital recovering from her accident. She doesn't remember the events of that fateful evening, although pieces of memories flood her mind.

Unbelievable finally reveals "A's" identity and the motive behind the threats and texts. As each girl begins to remember their past friendship with Ali, each slowly realizes that Ali just wasn't the sweet, innocent girl everyone loved. Ali kept secrets of her own. . . secrets that could have killed her.

I figured out "A's" identity after reading book 2: Flawless, however after reading the last chapter in Unbelievable, I just can't help but to wonder is there more to "A" and these four former best friends. I mean, the series isn't finished yet. . .
