In picture-perfect Rosewood, Pennsylvania, ash-blond highlights gleam in the winter sun and frozen lakes sparkle like Swarovski crystals. But pictures often lie--and so do Rosewood's four prettiest girls.

Hanna, Aria, Spencer, and Emily have been lying ever since they became friends with beautiful Alison DiLaurentis. Ali made them do terrible things--things they had to keep secret for years. And even though Ali was killed at the end of seventh grade, their bad-girl ways didn't die with her.

Hanna's on a mission to corrupt Rosewood's youth, starting with a very attractive sophomore. Aria's snooping into her boyfriend's past. Spencer's stealing--from her family. And pure little Emily's abstaining from abstinence.

The girls should be careful, though. They thought they were safe when Ali's killer was arrested and A's true identity was finally revealed. But now there's a new A in town turning up the heat. And this time Rosewood is going to burn.

Everyone has something to hide--especially high school juniors Spencer, Aria, Emily, and Hanna.

Spencer covets her sister's boyfriend. Aria's fantasizing about her English teacher. Emily's crushing on the new girl at school. And Hanna uses some ugly tricks to stay beautiful.

But they've all kept an even bigger secret since their friend Alison vanished.

How do I know? Because I know everything about the bad girls they were and the naughty girls they are now. And guess what? I'm telling.

Who is Casey Rhodes? Is she a no-nonsense realist or a hopeless romantic? A just-getting-by scholarship student or a sometimes Cinderella dating the cool, cultured heir to a media empire and New York City’s most eligible? At seventeen years old and already in her sophomore year at NYU, Casey sheds disguises effortlessly. It’s how she navigates school and avoids the second-guessing that’s plagued her since she and her boyfriend Marcus got together.    But then Casey starts hearing voices that terrify her so badly she flees to the remote beach town of Avon Shores where she can sort through her thoughts and reset. But the voices only get more intense and are now accompanied by visions of places she’s never been and people she’s never met, like Jake who’s lived in Avon Shores his whole life. There’s no way Casey could know him, yet she feels an immediate connection. And stranger still: he feels it too. Together they search for answers, finding only questions—about their connection, Avon, Casey’s memories . . . And whose voice is she hearing inside her head?

Being wanted isn't always a good thing.

For three long years, Hanna, Spencer, Aria, and Emily wondered what happened the night their best friend Alison disappeared. Now that all their questions have finally been answered, they can put this awful chapter of their lives behind them. Or so they think.

Not every story has a happy ending, especially when four pretty little liars have done so many wicked things. Will the girls get everything they've ever wanted? Not if I have anything to say about it.

Spencer stole her sister's boyfriend. Aria is brokenhearted over her English teacher. Emily likes her new friend Maya . . . as much more than a friend. Hanna's obsession with looking flawless is making her sick. And their most horrible secret yet is so scandalous that the truth would ruin them forever.

And why shouldn't I tell? They deserve to lose it all. With every crumpled note, wicked IM, and vindictive text message I send, I'll be taking these pretty little liars down. Trust me, I've got enough dirt to bury them alive.

Four gorgeous girls are telling very ugly stories.

First Emily, Aria, Hanna, and Spencer claimed they found a dead body in the woods behind Spencer's house, only to have it vanish without a trace. Then, when the same woods went up in flames, they swore they saw someone who's supposed to be dead rise from the ashes. And even after all that, the pretty little liars are still playing with fire. Call me heartless, but it's about time someone shut these liars up for good. After all, nobody likes a girl who cries wolf--least of all me. . . .

In Rosewood, Pennsylvania, four perfect-looking girls aren't nearly as perfect as they seem.

Aria can't resist her forbidden ex. Hanna is on the verge of losing her BFF. Emily is freaking out over a simple kiss. And Spencer can't keep her hands off anything that belongs to her sister.

Lucky me. I know these pretty little liars better than they know themselves. But it's hard keeping all of their secrets to myself. They better do as I say . . . or else!

In idyllic Rosewood, Pennsylvania, four very pretty girls just can't help but be bad. . . .

Hanna will do anything to be Rosewood's queen bee. Spencer's digging up her family's secrets. Emily can't stop thinking about her new boyfriend. And Aria approves a little too strongly of her mom's taste in men. Now that Ali's killer is finally behind bars, the girls think they're safe. But those who forget the past are condemned to repeat it. And they should know by now that I'm always watching. . . .

Everyone knows Chelsea Dawson. Day and night, her tens of thousands of followers on Instagram watch her every move. So when she goes missing from the sunny beachside town of Lafayette, it makes headlines.

The police are searching everywhere for her kidnapper, but when eighteen-year-old Seneca Frazier sees Chelsea's picture, she knows instantly who took her. Chelsea looks exactly like her friend Aerin Kelly's murdered sister - and Seneca's own mother, who was killed five years ago.

Seneca's suspicions are confirmed when the killer contacts her, threatening to hurt Chelsea if Seneca goes to the police with what she knows. Seneca makes the only move she can, reaching out to Aerin and Maddox and Madison Wright, her friends from Case Not Closed, an amateur crime-solving community. Together they go to Lafayette to work the case, to save Chelsea, and to bring the killer to justice.

But the killer has a plan of his own. He wants Seneca and her friends in Lafayette, but he wants them to play by his rules. One wrong step could mean the end for Chelsea - or the Amateurs.

No matter how close the liars get, A is always one step ahead -and ready to crush them completely.

Everyone has something to hide--especially high school juniors spencer, aria, emily, and hanna. Spencer covets her sister's boyfriend. Aria's fantasizing about her English teacher. Emily's crushing on the new girl at school. Hanna uses some ugly tricks to stay beautiful. But they've all kept an even bigger secret since their friend Alison vanished. How do I know? Because I know everything about the bad girls they were, the naughty girls they are, and all the dirty secrets they've kept. And guess what? I'm telling.

They're good girls . . but no one's perfect . . .

Mackenzie, Ava, Julie, Parker and Caitlin are five senior high-school girls who seem to have it all. Top grades, beautiful looks, music scholarships, sports captaincies... even the boys of their dreams. But there's just one small flaw in their apparently perfect facade. They're wanted for a murder they didn't commit.

Sure, they talked about killing rich bully Nolan Hotchkiss, but they didn't go through with it. It's just a coincidence that Nolan died in exactly the way they planned . . . right? Except Nolan wasn't the only one they fantasised about hurting in film class that day. And now someone seems to have found their list, and is carrying out their very particular revenges in their name.

Who is really behind these killings?

Who can they truly trust?

And who will be the next to die?

Everyone's dying to know the truth . . .

When Aerin Kelly was eleven, she idolised her seventeen-year-old sister, Helena, and they did everything together. They made Claymation movies and posted them to YouTube. They made fun of Windmere-Carruthers, the private school they attended, they invented new flavours for their parents' organic ice cream shop, and they dressed up their golden retriever, Buster. But when Helena went into senior year things started to change. Rather than being Aerin's inseparable sister, she started to push her away. Then, on a snowy winter's day, Helena vanished.

Four years later, Helena's body is found. Wracked with grief and refusing to give up on her sister, Aerin spends months trying to figure out what exactly happened to Helena and who killed her. But the police have no leads. A young, familiar officer named Thomas wants to help and suggests she checks out a website called Case Not Closed. Hesitantly, she posts, and when teenagers Seneca and Maddox show up on her doorstep offering to help investigate she accepts in desperation. Both have suffered their own losses and also posted to the site with no luck, so they are hoping this case might be the one they crack. But as their investigation begins, it seems that maybe it's no accident that they are all together, and that maybe the crimes have something - or someone - in common.
