You’ve probably seen the cover. A set of cold, steel bars and that neon-bright text that screams "psychological thriller." If you’ve spent any time on BookTok or scrolled through Amazon’s bestsellers lately, you know Freida McFadden is basically the queen of the "just one more chapter" binge. But The Inmate is a weird one. Honestly, it’s one of her most polarizing books.
People either love the breakneck pace or they’re literally yelling at the protagonist, Brooke Sullivan, for being—well, a bit of a disaster when it comes to common sense.
The setup is classic Freida. Brooke is a nurse practitioner who moves back to her hometown and takes a job at Raker Maximum Security Penitentiary. It’s a grim place. The kind of place where you shouldn't break the rules. But Brooke has already broken the biggest one: she has a history with one of the most dangerous men behind those walls.
The Messy Reality of Brooke and Shane
Shane Nelson was the high school golden boy. Quarterback, handsome, the whole deal. Now? He’s serving life for a triple murder. Specifically, a grisly night eleven years ago that left three of their friends dead.
Here is the kicker: Brooke’s testimony is what put him there.
She was there that night. She was almost a victim herself. But as she starts her new job at the prison, Shane starts whispering in her ear. He says he’s innocent. He says he was framed. And because this is a McFadden novel, Brooke starts to wonder if she sent the wrong man to rot in a cell.
It’s easy to judge Brooke. In fact, if you read the Goodreads reviews, "idiot" is a word that comes up a lot. She’s a mother, yet she’s making choices that feel like she’s walking into a woodchipper. But that’s the thing about McFadden’s writing—she leans into that "popcorn thriller" vibe. It’s not meant to be a gritty, realistic documentary on prison life. It’s a fever dream about trust and how easily our memories can be manipulated.
Why the Setting Actually Works
McFadden is a practicing physician in real life. You can tell.
The medical details at Raker feel authentic because she knows how a clinic runs, even a high-stakes one. When Brooke is suturing a wound or dealing with a dismissive head nurse like Dorothy, there’s a layer of realism that grounds the more "out there" plot points.
The prison isn't just a backdrop; it’s a pressure cooker. You’ve got the clanging doors, the specific rules about not sharing personal info, and the constant threat of "The Pit." It creates this claustrophobic feeling where Brooke’s bad decisions feel even more dangerous.
That Ending (No Spoilers, But Let’s Talk)
If you haven’t finished the book, stop reading about the plot right now. Seriously.

The ending of The Inmate is what everyone talks about. Most thrillers have one "big" twist at the end. Freida usually gives you two or three. Just when you think you’ve figured out who the actual killer was that night eleven years ago, she pulls the rug out.
Then she pulls the floor out from under the rug.
We get a dual timeline—the "Then" and the "Now"—which is a staple for a reason. It works. We see the night of the party unfold in pieces. We see the relationship between Brooke, Shane, and their friend Tim Reese. Tim is the "nice guy" who stayed behind, the one who wants to help Brooke. But in a Freida McFadden book, being the "nice guy" is usually a massive red flag.
The epilogue involving Brooke’s son, Josh, is what leaves most people's jaws on the floor. It shifts the entire perspective of the book from a story about a woman’s past to a terrifying look at "nature vs. nurture."
What Readers Keep Missing
A lot of people complain that Brooke is too gullible. "Why would she work at the prison?" "Why would she trust Shane?"
But look at her history. She lost her parents in a car accident. She’s a single mom struggling to make ends meet. She’s isolated. When you’re that lonely, a familiar face—even one behind bars—can feel like a lifeline. It’s a classic case of gaslighting, and Shane (and his mother, "Margie") are world-class at it.
Survival Tips for the Freida McFadden Universe
If you’re planning to dive into The Inmate or any of her other hits like The Housemaid, here’s how to actually enjoy them:
- Suspend your disbelief. If you want a 100% accurate portrayal of the legal system, read a textbook. If you want to be entertained, stay here.
- Watch the scents. McFadden loves using sensory clues. In this book, keep an eye (or nose) out for the smell of sandalwood.
- Trust nobody. Not the best friend. Not the boyfriend. Especially not the polite old lady.
- Read the epilogue twice. The real "holy crap" moment is almost always in the final three pages.
The Inmate isn't just a book about a prison. It’s a book about the prisons we build for ourselves out of guilt and bad memories. It’s messy, it’s fast, and it’ll probably make you want to call your therapist.
Actionable Next Step: If you’ve already finished The Inmate and need that same "trapped" feeling, pick up Ward D. It’s set in a psychiatric ward and carries that same medical-expertise-meets-nightmare energy that Freida does best. Just don't plan on sleeping until you finish it.
