When I first read we were liars, I didn’t know how deeply the story’s psychological twist would hit me, especially with its mix of trauma, grief, and that creeping sense of guilt tied to the Sinclair family. Even without giving away the twist ending, the book hints at a hidden truth connected to Cadence Sinclair or Cady, as everyone calls her and her fractured memories after Summer 16, when a fire incident changed everything. What kept me hooked was how E. Lockhart used memory loss and the idea of “seeing” things, almost echoing The Sixth Sense, which she once called an inspiration. The emotional weight felt even heavier later when the Prime Video adaptation came out on Amazon Prime Video, especially when episode 10, My Friends Are Lying in the Sun, delivered a dramatic reveal that mirrored the book’s major twist. Characters like Gat, Johnny, and Mirren linger in the story like shadows almost like dead people haunting the edges which added to the book’s rising popularity among early readers, turning it into a bestseller and favorite of BookTok.
Watching the TV series after reading the deluxe edition of the book felt like revisiting an old memory from a different direction. The season 1 finale offered a story version filled with heightened drama, new rhythms, and subtle adaptation changes that gave the familiar plot twist a fresh angle. The finale carried that same heavy emotional impact, leaning into the idea of an unreliable narrator whose mind hides a truth reveal waiting to break open. I’ve always appreciated how additional reveals in the show didn’t replace what the book did they simply shifted the perspective, making the tragedy and haunting atmosphere even sharper. After experiencing both, I can say that understanding the ending explained only adds to the tragedy’s pull, and even knowing the dramatic reveal doesn’t blunt its force; instead, it draws you deeper into the world of We Were Liars with a renewed sense of sorrow and fascination.
The Core Twist: Who Died in the Fire?
The fire on Beechwood Island killed Gat, Johnny, and Mirren. All three were trapped when the plan to burn down Clairmont went wrong, and they didn’t make it out. Their deaths are the central tragedy that reshapes the story and explains why they appear only in Cady’s fractured memories.
Cady is the only one who survived the fire. Her severe head injury and trauma led to her memory loss, causing her to unknowingly “spend time” with the cousins and boy she loved long after they were gone.
The devastating twist is that the Liars she interacts with throughout most of the book are not alive. The truth forces her to confront the guilt of her role in the accident and the grief she’s been unconsciously avoiding.
The Motive: Why Did They Burn Clairmont?
In the book of We Were Liars, the Liars Cady, Gat, Johnny, and Mirren decide to burn down Clairmont because they’re overwhelmed by the Sinclair family’s constant fighting over inheritance, property, and status. Every summer, they watch the adults manipulate one another, compete for favoritism, and twist every conversation into a power grab. The mansion becomes a symbol of everything rotten in the family: greed, entitlement, and a legacy built on appearances instead of love. Burning Clairmont feels to them like the only way to break that cycle.
Their plan is meant to send a message: destroy the thing the adults value most so the arguing will finally stop. The Liars believe that by wiping out the source of the conflict, they can force the family to rebuild in a healthier way. It’s an idealistic, reckless attempt to reclaim control and punish the toxicity they’ve been surrounded by for years. But their actions come with a tragic cost none of them fully anticipate until it’s too late.
The Final Line Meaning
In the book of We Were Liars, the final line “Be a little kinder than you have to” is a quiet but powerful statement about what Cady learns after uncovering the truth. She has witnessed firsthand how pride, greed, and emotional distance destroyed the Sinclair family and ultimately led to tragedy. The line serves as a reminder that cruelty isn’t always loud; sometimes it’s the choices we don’t make, the empathy we withhold, or the moments when we protect our ego instead of the people we love. Cady’s journey shows how easily harm can spread when kindness is treated as optional.
The message also asks readers to take something meaningful from the wreckage of the Liars’ story. If the Sinclairs had been softer with each other less competitive, less stubborn, less driven by image everything might have unfolded differently. By ending on this line, the book encourages a simple but challenging form of compassion: choosing kindness even when you’re hurt, tired, or tempted to pull away. It’s the one lesson Cady can carry forward, and the only one that has the power to break the cycle her family never could.
Book vs. Show Ending Difference
In the book of We Were Liars, the ghosts of Gat, Johnny, and Mirren are seen only by Cady, emphasizing her trauma and unreliable memory. In the show, the biggest change is that Aunt Carrie briefly sees Johnny’s ghost, suggesting the haunting extends beyond Cady. This shift gives the Amazon Prime adaptation a more supernatural tone and widens the emotional impact.
