The order the books were released — the default way to read the series.
Five students walk into detention; only four walk out alive. Simon Kelleher, the outcast behind Bayview High's cruel secret-sharing app, dies from an allergic reaction during detention, and the other four in the room — a jock, a criminal, a princess, and a brain, in classic high-school-movie shorthand — instantly become suspects when it turns out someone tampered with his EpiPen. Told in rotating first-person chapters from all four suspects, the book unravels which of them had the strongest motive, what secrets Simon was about to post about each of them, and whether his death was murder at all. The sequels widen the lens beyond the original four: One of Us Is Next introduces a new copycat game terrorizing Bayview a year and a half later, and One of Us Is Back brings the whole cast together again as their pasts catch up with them.
Karen M. McManus built her breakout hit around the classic locked-room mystery structure crossed with high-school clique archetypes and social-media-era secrets, and the trilogy keeps that same rotating-suspect, everyone-has-something-to-hide formula while raising the stakes and body count each time. It's fast, twisty, and unapologetically plot-driven, with each book functioning as a genuinely fair-play whodunit rather than just a vibes-based thriller.
Three: One of Us Is Lying, One of Us Is Next, and One of Us Is Back.
Publication order: One of Us Is Lying, One of Us Is Next, One of Us Is Back. Each book builds on the fallout of the last.
Yes. Karen M. McManus has described One of Us Is Back as the trilogy's final book, closing out the Bayview storyline.
Yes. One of Us Is Next is set eighteen months after the first book, brings back several of its characters, and spoils its central mystery.
No, it's an original mystery, though it draws on familiar high-school-movie archetypes (the jock, the princess, the criminal, the brain) and a Breakfast Club-style detention setup as its jumping-off point.
