You know that feeling when you finish a book and just sort of stare at the wall for ten minutes? That’s the Don't Believe It book experience. Honestly, it’s one of those rare psychological thrillers that actually earns the "twist" everyone keeps buzzing about on BookTok and Reddit. Most of the time, "unreliable narrator" is just code for a writer who couldn't figure out a plot hole. But with Charlie Donlea, it’s a surgical strike.
He doesn't just lie to you. He makes you want to be lied to.
The story drops us right into the humid, sticky atmosphere of St. Lucia. We're following Sidney Ryan, a documentary filmmaker who is basically trying to "Making a Murderer" her way into a career peak. She’s looking at the ten-year-old conviction of Grace Sebold, a woman accused of murdering her boyfriend, Julian, during a vacation that went south in the worst way possible. It’s got everything: a tropical paradise, a gruesome death, and a woman who has been rotting in a foreign prison claiming she’s innocent.
It's a vibe. A dark, messy, complicated vibe.
The Meta-Narrative of the Don't Believe It Book
What makes this specific story work isn't just the "did she or didn't she" hook. It's the way Donlea uses the medium of a documentary within the novel. You’re reading about a woman making a film, and as she uncovers "the truth," the world is watching alongside her.
It feels real.
Sidney Ryan is a great protagonist because she’s flawed. She isn't some altruistic seeker of justice; she wants ratings. She wants the "viral" moment. This creates a weird tension where you, the reader, start questioning if she’s even looking for the truth or if she’s just looking for the best story. It’s a meta-commentary on our obsession with true crime. We consume these people's tragedies like popcorn. Donlea knows that. He plays with that guilt.
There's a specific rhythm to the prose here. Sometimes it's clinical, like a police report. Other times, it's visceral. The heat of the Caribbean practically leaks off the page. You can smell the salt air and the underlying scent of decay.

Why the Twist Actually Sticks the Landing
Most thrillers fail in the final thirty pages. They pull a rabbit out of a hat that wasn't even on the stage.
But with the Don't Believe It book, the clues are there. They're just buried under Sidney’s ambition and our own desire to see Grace as a victim. Grace Sebold is written with such a haunting, quiet desperation that you find yourself rooting for her release. You want the system to be wrong.
The pacing is frantic.
One minute you’re in a slow-burn investigation, and the next, the floor drops out. Donlea uses short, punchy chapters that act like camera cuts. It makes sense, given the documentary theme. You’re seeing the "edit" of the story in real-time.
Wait. Let’s talk about the ending without spoiling it. It’s mean. It’s one of the meanest endings I’ve read in a long time. It doesn't give you the warm, fuzzy closure of a procedural drama where the bad guy gets handcuffed and the credits roll over a sunset. It leaves you feeling a bit sick.
That’s high-quality writing.
Realism and Legal Nuance in Donlea’s Writing
Charlie Donlea isn't just throwing darts at a map. He’s known for doing actual legwork regarding forensic science and international law. In Don't Believe It, the depiction of the St. Lucian legal system and the "Sugar Beach" murder (which echoes some real-life cases, though it's fictional) feels grounded.

He captures the helplessness of being trapped in a legal system that doesn't operate by your home country's rules.
- The Forensic Detail: He focuses on "micro-traces"—the things people miss when they're looking at the big picture.
- The Media Circus: How a hashtag can change a court ruling.
- The Psychology of Isolation: What ten years in a cell does to a person's memory of the "truth."
Is it perfect? No. Some of the secondary characters feel a bit like archetypes. The "skeptical producer" and the "jaded local cop" show up right on cue. But they serve the purpose of keeping the momentum moving toward that inevitable, crushing finale.
What Most People Get Wrong About This Story
A lot of readers go into this expecting a standard "wrongful conviction" trope. They think it's going to be a justice story. If you go in with that mindset, you're going to be frustrated. This isn't a book about justice. It’s a book about perception.
It’s about how we believe what we want to believe because the alternative is too uncomfortable.
The title isn't just a suggestion; it's a warning. "Don't Believe It" applies to the documentary, to the characters, and honestly, to your own instincts as a reader. You’ll find yourself flipping back to earlier chapters saying, "How did I miss that?"
He hid it in plain sight. That's the trick.
Actionable Steps for Your Next Read
If you’re ready to dive into the Don't Believe It book, or if you've already finished it and are looking for that same high, here is how to approach it.

First, pay attention to the dates. The timeline jumps are subtle but vital. If you lose track of the "then" vs. the "now," the ending won't hit as hard.
Second, look at the other works in this "universe." Donlea has a habit of connecting his stories. Characters like Rory Moore or Lane Phillips sometimes pop up or are referenced in his other books like The Suicide House or Some Choose Darkness. Reading them in a loose chronological order adds a layer of depth to the world-building that you’d otherwise miss.
Lastly, watch a real true-crime documentary right after you finish. The Staircase or The Jinx. You’ll see the tropes Donlea is skewering. You’ll see the way editors manipulate your emotions with a well-timed pause or a lingering shot of a grieving family member. It makes the book feel even more prescient.
Check the copyright page. Look at the publication history. This book came out in 2018 but feels more relevant in 2026 than it did back then. In an era of deepfakes and "fake news," a story about how easily we can be manipulated by a well-produced narrative is basically a survival guide.
Go buy a physical copy. Some books are meant for Kindles, but this one needs dog-eared pages and notes in the margins. You’re going to want to track the lies.
Trust me. Or don't. That’s kind of the point.
