Background On Pretty Little Liar Books

The Pretty Little Liars series consists of a gripping set of young adult novels by Sara Shepard that first began in 2006. The story centers around a group of four teenage girls-Aria Montgomery, Spencer Hastings, Hanna Marin, and Emily Fields-whose lives are shattered when their best friend, Alison DiLaurentis, mysteriously disappears one summer night. As the series unfolds, the girls are stalked by an anonymous figure known only as "A," who knows all their deepest secrets and isn’t afraid to use them to manipulate, torment, and expose them. The series explores themes of friendship, identity, secrets, trust, and revenge. Each character’s journey is filled with complicated emotional arcs, as they try to make sense of their past while grappling with the constant threats from A.

The first book introduces us to the characters and the mystery surrounding Alison’s disappearance, while each subsequent book builds upon these foundations, complicating relationships and uncovering more sinister truths. The series spans a total of 16 books, divided into multiple story arcs that take readers through twists, turns, and increasingly darker revelations. The core of the series lies in its tension and suspense, as the girls must confront the unsettling reality that their deepest fears and most closely guarded secrets are known by someone-someone who is always one step ahead.

Reading Order Explained

The Pretty Little Liars series isn’t just a simple tale of teenage angst or typical high school drama. Its narrative arc spans numerous books, side stories, and prequels that can make it a bit overwhelming to approach the series if you don’t know where to begin. So, understanding the correct reading order is essential to fully appreciate the complexity and unfolding mystery.

The main series follows a linear progression with each book representing a new chapter in the lives of the four central characters. The core of the series starts with Pretty Little Liars (Book 1), where Alison has been missing for over a year, and the girls start receiving ominous messages from “A”.

Prequel Series (The "The Perfectionists" Duology)

Before delving into the main series, it’s important to mention the prequel duology called The Perfectionists, which provides background on the characters and offers additional context for the universe Sara Shepard created. The Perfectionists introduces a new set of girls at Beacon Heights High School and gives readers insight into the mysterious events that set the stage for the original Pretty Little Liars series. The books in this duology are:

1. The Perfectionists
2. Goodbye, Perfect

These prequel books are not essential to understanding the main plotline of Pretty Little Liars but can enrich your experience if you enjoy the world Shepard has built.

Companion Series (The "Lying Game" Series)

In addition to Pretty Little Liars and its prequel, Shepard has also written a companion series known as The Lying Game. While not directly connected to Pretty Little Liars, both share similar themes of betrayal, mystery, and dark secrets. However, these are separate narratives and are not crucial to understanding the central plot of Pretty Little Liars.

What I Like About The Series?

There’s a lot to appreciate about the Pretty Little Liars series, particularly for fans of suspenseful and character-driven stories. Here are a few reasons why this series stands out:

1. Complex Characters

   Each of the four main characters-Aria, Spencer, Hanna, and Emily-has a distinct personality and struggles with their own unique set of challenges. The depth of each character’s backstory and the evolution of their individual arcs throughout the series keep the reader invested. You’ll find yourself rooting for them, despite their flaws, because each girl has their own journey to self-discovery. The growth and changes they undergo make the story feel personal and intimate.

2. Unpredictable Plot Twists

   The constant sense of mystery and the looming presence of ’A’ keeps readers on the edge of their seats. Each new revelation feels like a puzzle piece, adding complexity to the overarching mystery. The unpredictable plot twists, the shifting dynamics between characters, and the ongoing game of cat-and-mouse with ’A’ create an atmosphere of perpetual tension that makes it impossible to put the book down.

3. Themes Of Friendship And Betrayal

   At its core, Pretty Little Liars is a story about friendship. The bond between the four girls is tested time and again as secrets are revealed and trust is shattered. Watching them navigate their relationships, rebuild trust, and ultimately support each other through the turmoil is deeply engaging. The exploration of betrayal and how it shapes personal identity is both poignant and dramatic.

4. A Fast-Paced Read

   The books are quick reads, thanks to their engaging writing style and short chapters. The pacing makes it easy to get sucked into the world Shepard has created. With cliffhangers and constant tension, it’s easy to power through the books in a binge-worthy manner.

5. The TV Show Tie-In

   If you’ve ever watched the Pretty Little Liars TV series, you’ll find that the books and the show share many similarities, but the plotlines often diverge. The books offer a different experience than the show, and fans of both mediums will appreciate the variations. If you love the drama and suspense of the TV adaptation, reading the books will provide additional context and deeper insights into the characters.

Should You Read Pretty Little Liar Books In Order?

Absolutely, yes. If you’re planning to immerse yourself in the Pretty Little Liars universe, reading the books in order is essential. The series relies heavily on an overarching mystery that develops across the books, and reading them out of sequence could result in missing crucial plot points, character development, and plot twists. The series is designed to build upon itself, with each book revealing new clues and advancing the characters’ arcs in ways that would be confusing without following the correct order.

Furthermore, the books are packed with secrets and revelations that unfold piece by piece, and skipping ahead would spoil the enjoyment of discovering these twists on your own. To get the full experience, it’s best to stick to the original reading order, allowing the suspense to build as it was intended.
