Pretty Little Liars is a series of young-adult novels by author Sara Shepard, beginning with 2006's inaugural entry of the same name. The series follows the lives of four girls – Spencer Hastings, Hanna Marin, Aria Montgomery, and Emily Fields – whose clique falls apart after the disappearance of their leader, Alison DiLaurentis, in the 7th grade. Later, when the girls are juniors in high school, Alison's body is found, and they begin receiving various messages from someone using the alias "A" who threatens to expose their secrets and get revenge on them for what Alison did to "A".
The novels explore several serious issues such as bullying, murder, drug addiction, underage drinking, eating disorders, homosexuality, peer-pressure, infidelity, and mental illness. Moral ambiguity and the consequences of lying are featured prominently in the series; the girls constantly create their own problems through their unwillingness to tell the truth about certain events and misdeeds they have done.
The novels have frequently appeared on the The New York Times Best Seller list. In 2010, a television series loosely based on the novels began airing. The twelfth book in the series, Burned, was released on December 4, 2012. A prequel, Ali's Pretty Little Lies, was released on January 2, 2013. Additionally, a thirteenth book, Crushed, is set to be released June 4, 2013. The fourteenth and last book, Deadly, will be released in December 2013.
The series is loosely divided into three arcs of four to five books each, chronicling the introduction and reveal of each "A". The series follows the lives of four teenage girls;— Aria Montgomery, Emily Fields, Hanna Marin, and Spencer Hastings (nicknamed the Pretty Little Liars or simply the Liars) — whose clique falls apart after the disappearance of their best friend, Alison DiLaurentis. One year after her disappearance, they begin receiving text messages from an anonymous source, "A," who threatens to expose their secrets; including long-hidden ones they thought only their close friend Alison knew. But shortly after the messages begin, Alison's body is discovered. The books progress forward as the four girls try to figure out who "A" is.
Although the series features an extensive cast of characters of varying significance, the novels focus predominantly on seven main characters:
- An extremely competitive girl who strives for perfection in everything she does. A high-strung over-achiever, Spencer is willing to do whatever it takes to win, often to the detriment of herself and others. She is often quick to jump to conclusions and suffers from IED. Spencer was a half-sister to Alison and Courtney DiLaurentis, her father having had an affair with Jessica DiLaurentis around the time of Spencer's conception. Spencer's parents later divorce when the affair comes to light. She attends a summer program at Penn to improve her GPA. Spencer has an ongoing feud with her older sister, Melissa, who is equally competitive. Throughout the book series, the two argue over the implications of their individual successes in life, such as becoming valedictorian and having award-winning essays.
- A pretty, popular girl who used to struggle with both bulimia and anorexia due to insecurities about her appearance. While in seventh grade, Hanna was very overweight and developed complicated eating problems, including binge eating from stress often followed by a bulimic episode. Flighty and occasionally air-headed, Hanna often acts purely on impulse. In Alison's absence, she became best friends with Mona Vanderwaal, Ali's previous bullying target, and they transformed themselves into Rosewood's new "It" girls. Hanna's parents divorced when she was twelve, after her father had an affair. She lives with her mother and would rarely see her father, especially after he started dating an average-looking nurse named Isabel. Hanna dislikes her father's new wife, Isabel, and her daughter, Kate, with whom she forms a rivalry. For a short time Hanna is sent to a mental institution, her father believing her eating disorders would resurface due to stress. Prior to Twisted, Hanna is involved in a car accident, which leaves another girl badly injured; she covers up her involvement with the help of the Liars.
- An artistic, bubbly, independent girl whose family moved back to Rosewood after her father took a three year sabbatical in Iceland. Prior to Alison's disappearance, Aria became aware that her father was having an affair with Meredith, a student of his at the local college. Having promised her father to keep the affair a secret, Aria is kicked out of the house and goes to live with her new boyfriend, Sean Ackard, after the first "A" reveals the affair to her mother. Her parents divorce and Aria's father marries Meredith who soon becomes pregnant. Aria often feels out of place in Rosewood and tends to be attracted to older, more worldly men, which frequently causes her conflicts. For example,her relationship with Ezra Fitz, her AP English teacher, resulted in Ezra losing his job at Rosewood High. After a near-death experience, she is overcome with guilt and decides to confess to accidentally killing Tabitha (unaware she was not actually responsible for Tabitha's death).
- Emily is a shy, dedicated swimmer. In "Flawless" she tells her parents she wants to quit swimming, but once she is made captain she changes her mind. She was in love with Alison, and kissed her once back in seventh grade. A fact which she takes great pains to hide. She develops feelings for a new girl named Maya, resulting in a secret relationship, but she is then outed by the first "A" when a picture of them kissing in the photo booth at the Kahn party is passed out at a swim meet. Although at first her parents make attempts to "de-gay" her, they eventually come to accept her and her sexuality. After she and Maya break up, Emily meets a guy named Isaac at a church event, and realizes that she's bisexual. They start dating and Emily loses her virginity to Isaac, whom she later breaks up with. It was revealed in Twisted that Emily had gotten pregnant from her first time with Isaac and hid it from her family by staying with her sister over the summer. She gave birth to a baby girl, Violet, and was going to give her to Gayle (her friend's extremely rich boss) for money but she changed her mind and gave the baby to the Bakers, a family she met through an adoption site. Emily's change in heart on who to give the baby to greatly anger Gayle, who later threatens both Emily and the baby. Even after the baby fiasco, Emily receives an athletic scholarship to attend UNC.
- An extremely popular, beautiful, and cruel girl. When she and her twin sister Courtney were younger, Alison was jealous of her more popular sister and forced Courtney to impersonate her, at the same time tormenting Courtney to the point that Courtney got angry and got into a physical fight with her. When the doctors were called by girls' parents, Courtney panicked and revealed that Alison was threatening her and forcing to impersonate her. Alison (who was acting very innocently all the time) claimed it was not true and decided that her sister had to go (allegedly for everyone's safety). In the outcome, Alison's master plan worked: Courtney was recognized as a paranoid schizophrenic. Her family moved then to Rosewood to avoid attention and changed their surname Day-DiLaurentis to DiLaurentis. In the beginning of sixth grade her twin Courtney successfully tricked their mother Jessica into taking Ali to the mental hospital. Alison blamed the liars for ruining her life and swore revenge. She was the second "A" and killed Courtney, Jenna and Ian. Later on she tries to kill the girls in her Poconos home but they manage to get out. Alison is left inside and it's unknown whether she died or not. She threatened Courtney to be her, so she would seem crazy, and sent away. She kills her sister by pushing her into a hole that was originally made for a gazebo, accompanied by an unknown person.
- Courtney was the good twin of Alison who the girls knew as Ali. Courtney since childhood was tormented by her twin sister (despite their initial friendship). Alison was always jealous of her more popular sister and forced Courtney to impersonate her, at the same time tormenting Courtney to the point when angry Courtney got into a physical fight with her. When the doctors were called by girls' parents, Courtney panicked and revealed that Alison was threatening her and forcing to impersonate her sister. Alison (who was acting very innocently all the time) claimed it was not true and decided that her sister had to go (allegedly for everyone's safety). In the outcome, Ali's master plan worked: Courtney was recognized as a paranoid schizophrenic. In the beginning of Alison's sixth grade, Courtney successfully tricked their mother Jessica into taking Ali to the mental hospital and she become Ali the Liars knew. Even though Courtney was mean to everyone in their school, she didn't want to be; she only did because she was pretending to be Alison. If she acted nicer to people, her family would notice the change, so Courtney always acted wrong despite her being good.
- The main antagonist of the series. "A", is an anonymous extortionist who is privy to the Liars' deepest and darkest secrets, and uses these secrets to exact revenge on the Liars for (often) perceived wrongdoings. There are three different "A" characters throughout the series. The first "A", Mona Vanderwaal, was able to discover the Liars' secrets by reading Alison's old journal. During a physical confrontation with Spencer Hastings, Mona was pushed over the edge of a quarry and died. The second "A" is the "real" Alison DiLaurentis, who was sent away to a mental hospital in place of her twin sister, Courtney. She later was said to have died in a house fire, while attempting to kill the Liars. A third "A", whose identity is currently unknown, begins tormenting the girls following an incident in Jamaica during spring break, prior to the events of Twisted.

|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.

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 discovers he actually has a wife and child, and he is 33 years old. 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.
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 is 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. In the end, 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.
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. Hanna has a happy Christmas, despite the fact that she thinks someone other than Kate has been watching her every move.
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, she is surprised by her boyfriend from Iceland, Halbjorn. Halbjorn tells her that he's running from the Icelandic police who are 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 get married. At the hotel, they attend a magic show involving two panthers, which 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 released the panthers after all. Aria goes to the courthouse and confesses to forging Ella'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 shows that he has done these things in the past, including trying to blow up a demolition office. Aria is satisfied with breaking up with him, but is paranoid about someone following her.
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.
