One of Us Is Lying by Karen M. McManus - Introduction
I had no idea how much a high school mystery could make me rethink the way we judge people so quickly. When I started One of Us Is Lying by Karen M. McManus, I thought it was just going to be another typical YA thriller, but it turned out to be so much more. The surprising insight? How easily we put people into neat little boxes—like the "jock," "nerd," or "outcast"—without really knowing their stories. This book really made me pause and think about the layers beneath the surface, especially in a setting as charged as high school.
I picked it up because I love a good mystery thriller with a dash of contemporary fiction and a bit of romance—plus, the buzz around it being a standout in the Young Adult genre was hard to ignore. And honestly, the audiobook version made it a breeze to get through the 360 pages in about 8-9 hours, perfect for those long commutes or cozy evenings.
If you’re someone who enjoys stories that keep you guessing but also dive into real, relatable issues—like friendship, identity, and trust—this is definitely for you. It’s got crime, secrets, and even touches on LGBT themes, so it’s rich and layered without feeling overwhelming.
So, if you want a book that’s thrilling but also makes you think about the complexity of people around you, I’d say give this one a shot. You might just find yourself looking at your own high school memories in a new light.

About Book Author - Karen M. McManus
Tonight, we have a truly special guest. Karen M. McManus didn't start out as a full-time novelist; in fact, she navigated the world of marketing before the compelling urge to write these gripping stories took hold. What's interesting about Karen is how a classic film, The Breakfast Club, sparked a darker "what if" question in her mind, a question that eventually grew into her breakout novel, One of Us Is Lying.
- She possesses an uncanny ability to delve into the intricate social dynamics of youth, weaving mysteries that feel both shocking and relatable.
- It's a talent you see shine through in her other page-turners like Two Can Keep a Secret and The Cousins, where every character has a secret.
Karen’s journey, from observing human behavior in one field to crafting complex characters in another, gives her a distinctive perspective. She understands the art of suspense and the delicate balance of trust and suspicion, making her uniquely qualified to explore the thrilling, often perilous, world of teen thrillers where nothing is ever quite as it seems.

Book Review
I picked up "One of Us Is Lying" by Karen M. McManus expecting a typical high school mystery, but what I got was a layered, character-driven thriller that kept me guessing until the end. The premise—five students walk into detention, and only four walk out—immediately grabbed my attention, and I was hooked from the first chapter.
One of the book's strengths is its multiple perspectives. Each character—Bronwyn, Addy, Nate, and Cooper—has a distinct voice that adds depth to the story. For instance, I loved how Bronwyn’s academic pressure contrasted sharply with Nate’s troubled background, making their motivations feel relatable and real. McManus's writing style is engaging and flows well, which kept the pacing brisk and made it hard to put down.
However, I felt that some plot twists were a bit predictable, especially for seasoned mystery readers. While the character development was strong, I wished some of the secondary characters had more depth. They often felt like stereotypes rather than fully fleshed-out individuals.
Comparing it to similar YA thrillers like "One of Us Is Next" or "A Good Girl's Guide to Murder," I found "One of Us Is Lying" to have a more compelling central mystery, but it lacks some of the emotional weight that "A Good Girl's Guide" delivered.
Overall, I really enjoyed my reading experience and would recommend it to fans of YA mysteries and thrillers. If you’re looking for a light read or prefer straightforward plots, this might not be for you. But if you love character-driven stories with twists, dive in!
Final Thoughts
If I'm being honest, I really enjoyed One of Us Is Lying. The twists and turns kept me guessing until the end, and I appreciated how it tackled themes of friendship and betrayal. My overall takeaway is that not everything is as it seems, and sometimes, the truth can be the most dangerous thing of all.
I'd definitely recommend this if you're a fan of young adult mysteries or enjoy a good whodunit. However, skip this one if you're looking for a light, feel-good read—it's definitely more on the darker side. The thing that surprised me most was how well-developed the characters were; I found myself genuinely invested in their stories.
Months from now, I think the idea that everyone has secrets will stick with me. I wouldn't mind reading it again, but I’d recommend the full book over a summary. There’s something about the suspense and the character dynamics that just doesn’t translate in a quick recap.
Overall, my reading experience was engaging and thought-provoking. I found myself reflecting on it long after I turned the last page, and I think that speaks volumes about its impact.
