Pretty Little Liars is a series of young adult novels by Sara Shepard. Beginning with 2006's initial novel of the same name, the series follows the lives of four girls—Spencer Hastings, Hanna Marin, Aria Montgomery and Emily Fields.

The novels appeared on The New York Times Best Seller list for 62 weeks. The series spawned a media franchise with a television series adaptation loosely based on the novels which debuted on June 8, 2010, on ABC Family. The franchise has been licensed by Amazon.com's Kindle Worlds range of non-canon ebooks.

Overview

The series is loosely divided into arcs, chronicling the introduction and reveal of each "A". Set in the suburbs of Rosewood, Pennsylvania, the series follows the lives of four teenage girls nicknamed the Pretty Little Liars or simply the Liars, whose clique falls apart after the disappearance of their queen bee leader, Alison DiLaurentis. Three years after her mysterious disappearance, the girls begin receiving intimidating messages from an anonymous character named "A". "A" threatens to expose their secrets, including long-forgotten ones they thought only Alison knew. Shortly after the messages begin, Alison's body is discovered buried in her yard. The books progress with the four girls trying to figure out the identity of "A" and facing many dangerous obstacles and twists as they do so.

Characters

The series has many characters, most of them recurring. The main characters are:

Spencer Hastings: Spencer is a headstrong, intelligent, overachieving girl who comes from the wealthy Hastings family and is usually forced into winning everything. She has wavy blonde hair and often wears preppy outfits when not in Sports clothes.

Hanna Marin: Hanna is the self-absorbed, popularity obsessed, strong, and fierce "it-girl" of the group following Alison's disappearance. She suffers from an eating disorder, about which she received taunts from Alison. She is Jewish with long dark brown hair she often dyes auburn.

Aria Montgomery: Aria is a quirky and artsy girl who, at the beginning of the books, is trying to find herself. She is very tall and pale with dark black hair that she occasionally highlights.

Emily Fields: Emily is considered the jock of the group, being a physical, loyal girl who struggles with her sexuality. Near the end of the series she also struggles with depression and suicidal thoughts. Emily is Catholic and described with red hair and muscular frame.

Alison DiLaurentis: Alison is the former "Queen Bee" of her clique, consisting of Spencer, Hanna, Aria and Emily. It is later revealed that the Alison the girls thought they knew was her twin sister, Courtney. "Real Ali" was friends with Naomi Zeigler and Riley Wolfe up until the sixth grade, when Courtney took her place. She had supposedly been killed at the beginning of the series. However, she is revealed to have been alive and also their tormentor "A" as she was mistaken for her twin sister Courtney, who pretended to be her. Alison was sent to The Preserve at Addison-Stevens, a rehab facility for mentally ill patients, which she believed was the Liars' fault, and has been plotting revenge ever since.

Her identical twin sister, Courtney DiLaurentis, debuted in Wanted after the TV show began in 2010. In the prequel, Courtney-as-Ali started disappearing in the last chapter and getting almost killed numerous times, until the end of the series (Vicious) when Ali-as-Courtney came out and started becoming friends with her twin "Ali" again after rehab with Tabitha and Iris, two lookalikes of Ali, all in the penultimate chapter.

In the book, their older brother's name is Jason DiLaurentis and their half-sisters are Melissa and Spencer Hastings.

Courtney DiLaurentis: "Alison", the one who originally befriended the four girls in the sixth grade, is later revealed to be actually Courtney in the books (often referred to by the Liars as Our Ali, or Their Ali.) She is the third child to Jessica and Kenneth. The twins were described to be inseparable as children, but Alison started to exhibit a vicious jealousy towards Courtney as they grew up, and the close bond deteriorated completely when she once tried to drown Courtney. Probably in a psychological phenomenon known as projection, Alison managed to convince, and possibly brainwash, Courtney at home and at school that she indeed was the jealous one. She made her refer to herself as Alison, adamantly, to their parents and teachers, her motive being that her sister would eventually be detained for insanity. Her plan eventually worked, and was sent to The Preserve at Addison-Stevens after a physical argument with Alison. But years later in a fit of vengeance on a rare visit home, Courtney managed to swindle a plan to trick their parents that Alison was Courtney when it was time to leave, Ali's claims that she was Ali making her parents believe her even less. Subsequently, Courtney morphs into "Queen Bee Ali" and, out of pure chance, befriends the Liars up until the night of her infamous disappearance when she was killed and buried by the real Alison DiLaurentis and her accomplice Nick Maxwell.

A: A is the main antagonist of the series, being, for the most part, an anonymous character who relentlessly torments many characters, in particular the Liars. Mona Vanderwaal, Alison DiLaurentis and Nick Maxwell are discovered to be A. Mona became A due to Alison and the Liars being responsible for The Jenna Thing, which burned her too. However, she is killed when Spencer pushes her off a cliff face and her neck is caught between rocks. However, a new "A" rises, this time even more determined to hurt the Liars. This A is revealed to be Alison herself who wanted revenge on the Liars for ruining her life and Nick, who is revealed to be her accomplice.

The book begins with the girls vacationing in Jamaica and Emily seeing a girl who she believes is Ali, the girl claims she is called Tabitha but acts strangely which just confirms the girls suspicions. Throughout the rest of the book, details about that fateful vacation emerge, such as the girls pushing "Tabitha" off a building to her death. In the meantime, Noel, Aria's boyfriend, has an exchange student, from Finland, come to live with him. Instead of being the nerdy boy, Klaudius, that Noel expected, the exchange student turns out to be a gorgeous blonde, Klaudia, who tries to steal Noel from Aria. Aria ends up accidentally pushing Klaudia off of a ski lift as an act of self-defense; however, Klaudia uses that information against Aria.

Gayle is murdered by "A" and it is revealed that she was Tabitha's stepmother. Tabitha's father speaks at Gayle's funeral, and announces that Tabitha's autopsy showed no trace of alcohol, meaning that she was murdered.

It is revealed that prior to the events of Twisted, the Liars covered up Hanna's involvement in a car accident that left another girl, Madison, badly injured. While on a school-sponsored cruise in the Caribbean, the Liars uncover clues that suggest "A" is more than one person. They begin to suspect Naomi Zeigler of being "A", after she befriends Hanna (who is unaware that Madison is Naomi's cousin) and attempts to sabotage Spencer's new relationship. Aria becomes friends with a boy named Graham, only to discover he is Tabitha's ex-boyfriend, leading the Liars come to believe that Naomi and Graham are working together as "A". Meanwhile, Emily falls for a stowaway, Jordan, unaware that she is a thief on the run from the authorities. After an explosion on the boat, the Liars go off on their own to bury "evidence" of their connection to Tabitha (Tabitha's locket, which "A" had planted for Noel to find). "A" tampers with their lifeboat, nearly stranding them in the middle of the ocean. The near-death experience pushes the girls into wanting to confess about killing Tabitha. However, as they make plans to come clean about everything, they discover that they were not responsible for Tabitha's death at all: She had been bludgeoned to death by "A". The Liars finally come to believe that "A" is, in fact, Alison, as Emily reveals that she may have helped Alison escape the burning Poconos house in Wanted, and now they have to track down her accomplice as well.

Set between Unbelievable and Wicked, the book is told from the point of view of the second "A", Alison DiLaurentis, as she spies on the girls during their Christmas vacation. The novel is divided into a series of four short stories, with each one focusing on the exploits of a specific girl. Spencer: Spencer and her family go to Nana Hastings mansion in Florida, and Spencer falls in love with a tennis player named Colin at the country club. Melissa seems to be helping Spencer win Colin's heart, but Colin ends up taking an interest in Melissa. During the trip, Spencer and her mother also run into Mrs. DiLaurentis several times, and Spencer is confused by her mother's strange behavior around Mrs DiLaurentis. Spencer also decides to fight for Colin. After Colin dumps Melissa to go out with her, Spencer and Melissa discover that Colin's actually 33 years old and also has a wife and child. Spencer and Melissa decide to team up to get revenge on Colin by putting crushed Viagra in his Aminospa vitamin water right before his important tennis game. In the end, they all have a fun vacation, but Spencer worries that someone has been following her. Melissa and Spencer seem to briefly make up in this, hence the sisters' wary friendship in Wicked. Emily: Emily is asked to go undercover as Santa Claus at the new mall, in order to catch 4 girls who work as elves there, who are suspected of vandalizing Christmas decorations around town, including Emily's mom's baby Jesus ceramic figure. The 4 girls, who call themselves the "Merry Elves", take a liking to Emily, and it's revealed that one of the girls, Cassie, was close with Alison. Emily accompanies the girls on their biggest prank yet, but Emily's mom uses her phone to track her, and the Merry Elves get caught. Eventually, the elves forgive Emily after she bails them out of jail. In the end, everyone realizes the true meaning of Christmas, but Emily can't shake off the weird feeling that someone is following her. It is revealed that A is blonde (she will later be revealed as Alison) as Emily sees a blonde figure run off. Hanna: Hanna joins a boot camp after thinking she gained too much weight at a holiday party. She develops feelings for the instructor, Vince. She also develops a rival, Dinah, another girl who also likes Vince. After competing for Vince's affection, she and Dinah become friends after catching Kate making out with the mall's new Santa (prior to Emily), something which Hanna also photographs. After agreeing to stop chasing Vince, she celebrates by going out for drinks with Dinah, where Dinah admits she knew Alison. Hanna goes home drunk, causing her to oversleep. As she arrives at boot camp, she discovers Vince and Dinah kissing, revealing that Dinah only pretended to be friends with Hanna to have Hanna let down her guard. Hanna flees the scene, devastated, and is confronted by Kate, who, after receiving a tip-off, followed Hanna around, taking unflattering photos of her at boot camp, which she threatens to put on Facebook. Hanna counterattacks by showing Kate the pictures of her and Santa, causing Kate to back off. Hanna also improves her relationship with her father, who gives Hanna her grandmother's Cartier locket for Christmas/Hanukkah. Hanna has a happy Christmas/Hanukkah, despite the fact that she thinks someone other than Kate has been watching her every move. Some of what Dinah said may be true such as she knew Alison. But it is likely she made most of it up to get Hanna's trust. Aria: Aria goes with her father and Mike to Bear Claw Resort, but leaves to go back home after finding out that Byron invited Meredith along as well. Upon arriving at home, Aria's surprised to see Halbjorn, an old boyfriend of hers from Iceland. Halbjorn tells her that he's running from the Icelandic police who're after him because he protested against the demolition of a puffin sanctuary. Unfortunately, his travel visa only lasts for a week. Aria proposes the idea of marrying him, and the two head off to Atlantic City to elope. At the hotel, they attend a magic show involving two panthers, which greatly angers Halbjorn, who cares a lot about the environment. After getting married the following day, which requires Aria to forge her mother's signature and lie about her age, they go to the place where the panthers are kept. After convincing Halbjorn not to release the panthers, they go back to the hotel. The next morning, Aria wakes up to find Halbjorn gone and his clothes missing as well. On the lobby's TV, Aria sees that Halbjorn ended up releasing the panthers anyway. Aria goes to the courthouse and confesses to lying about her age and forging her mother's signature, making the marriage null and void. Upon returning to Rosewood, she is joined by Mike and Byron, who know nothing about her marriage. As they watch TV, it shows that Halbjorn has been caught, and it also reveals that he's done these sorts of things in the past, including trying to blow up a demolition office. Aria's satisfied with breaking up with him, but is paranoid about someone following her. In Wicked, it's briefly stated that Aria and Meredith did converse about the baby. The book ends with a sign-off from the new "A", (as always) who says that the Liars' lives are going to get a lot worse. All of which comes true...
