More About the Author

Hello! I'm from outside Philadelphia, lived in New York for a long time, Arizona for less time, and now I'm in Pittsburgh, PA, which is way nicer than it sounds.

I've always been a writer. I made up stories about my sister's blanket, BeeBee, when I was four. From there I wrote about squareheaded creatures, an environmental saga about little yellow men who live in vegetable gardens, teenage dramas well before I was a teenager, a book series about a Japanese girl who finds out her ancestors are samaurai (and she must be one, too), a bunch of arty short stories, and some books that maybe you've heard of. The PRETTY LITTLE LIARS series is based on my experiences there...kind of. Sort of a hyperbolic version of them. Plus some random stuff thrown in.

I've also written THE LYING GAME, which is about a dead twin and an alive twin, THE HEIRESSES, which is about a rich family's curse, and THE PERFECTIONISTS, which is about five somewhat strangers who get everything they wanted...but that comes at a price. I wrote THE VISIBLES, which is about jackalopes and mental illness, and EVERYTHING WE EVER WANTED, which features a guy who discovers his ex lives on a commune.

It seems like only yesterday that Hanna Marin, Alison "Ali" DiLaurentis, Spencer Hastings, Aria Montgomery, and Emily Fields were carefree, fun-loving seventh graders at posh private school Rosewood Day. Planning sleepovers, gossiping about boys, braiding each others hair, sharing secrets. But like the flip of a switch, everything changed. Ali mysteriously disappeared, and the four other girls parted ways. That was years ago. Now the mysterious "A" has dredged up the past once more; barraging Hanna, Spencer, Aria, and Emily with painful memories of the past via text messages. It's obvious that "A" is Ali's killer; but if the girls tell, one of them will be the next to die.

Hanna Marin has always been so full of life. Shopping as much as possible, prancing around in sky-high platforms, and perusing fashion and gossip websites to get her daily fix of all things celebrity. Seeing her lying in a hospital bed, unable to speak, bruises dotting her face, in a coma seems completely out of the ordinary. Aria Montgomery, Spencer Hastings, and Emily Fields know Hanna, and this isn't her. But it is a reminder of just how close "A" truly is to them; and how "A's" threats are absolutely true. But Hanna isn't the only one in turmoil at the moment.

Emily Fields has suddenly been shunned by her family. The fact that she has come out of the closet, so to speak, shames her parents, and even her sister, and has landed her on a one way trip to Iowa to live with her strict aunt and uncle, along with their children. Iowa seems like the worst place on earth. But some of the people there are actually pretty cool; and very into Emily.

Spencer Hastings has finally come to the realization that she has black-outs at times, and can't help but wonder if she is the one responsible for Ali's death.

Being an avid fan of the previous three books, I eagerly awaited "Unbelievable." When I finally got it, I devoured the book in one day!

Ms. Shepard's writing is excellent like always, and there are plenty of plot twists to keep you reading til the end. I thought I had figured out who A was several times in the beginning, but none of those theories were correct.

That being said, I figured out who A was right before the girls did, so that reveal wasn't as shocking as I hoped. However, the ending pages were filled with unresolved storylines and plot twists that left me on the edge of my seat.

I would definitely recommend this book, and the whole series, to anyone.

The answer is obviously not, as there are four more books in the series. When it was first put out this book was supposed to be the last, but the author agreed to put out more due to pressure from the publisher. (Thanks publishers!)

The now not so fab four have all new problems on their hands. Emily has been sent out to the country, only to find that her problems will follow her wherever she goes. Hanna's still in a coma, but will she still remember A's identity when she wakes up? Aria's trying to piece not only her life together, but also the pieces to the enigma that is A. Meanwhile Spencer still hasn't learned her lessons about cheating or forbidden fruit- lucky for her, A is an ever patient tutor in those matters...

I liked this book for the most part. I agree with many reviewers who felt that A's identity seemed a bit rushed & anti-climactic, so I was relieved that there were 4 more books in the series. This means that while you know who was A, there was undoubtedly someone in the back pulling the strings ensuring that "A" discovered the right secrets and sent the right texts. That being said, I was glad to finally see the humanity in many of the families. The whole "mean, ruthless, and competitive" thing made for good reading for a while, but it wasn't entirely believable that everyone would turn their backs on their kids. Whether that will continue into the next book is anyone's guess, but it was still nice to see that some of the parents really cared for their kids' well being.

Spencer, Hanna, Aria, and Emily are back, some in better state than others, and ready to bring down A. When we last left the pristine Rosewood Hanna had just discovered who A was, but she knew too much and A made sure she couldn't say anything by "accidentally" hitting her with a car. Now as Hanna fights for her life, the other three girls have to clean up the mess that A has made.

Spencer finally remembers what happened the night of Ali's death and what she remembers isn't good. Could she really have killed Ali? Not only does she have to deal with the thought that she could have really killed her best friend but she's got to reason with the guilt of stealing her sister's AP Economics paper which got Spencer nominated for an award her sister should have won. With the feeling that A is constantly breathing down her back will Spencer be able to keep her cool composure or will she finally pop?

After A let it leak that Emily likes girls, Emily's been living on the edge of sanity. Her parents don't know what to do with her so they send her off to her hyper conservative relatives in Middle of Nowhere Iowa. When she arrives Emily knows she won't last long, then she meets Trista, an interesting girl who seems to understand Emily and doesn't mind talking to her. Will Emily last, or will she flee back to Rosewood and hope that she is accepted by those who love her most?

Aria's been kicked out of her mother's house after her mom found out Aria had been keeping the secret of her father's affair a secret for the past three years. Once again we have A to thank for unveiling this bit of information. With nowhere else to go Aria moves in with her father and horrifyingly peppy girlfriend Meredith. All Aria wants is for her life to go back to normal.
