One of Us Is Lying

Karen M. McManus’s sensational debut novel, One of Us Is Lying, is a high-octane psychological mystery often described as The Breakfast Club meets Pretty Little Liars. The story revolves around five high school students at Bayview High who are sent to detention together: Bronwyn (the brain), Addy (the beauty), Nate (the criminal), Cooper (the athlete), and Simon (the outcast). Simon is the infamous creator of the school’s notorious gossip app, which broadcasts his classmates' deepest, darkest secrets. Before detention ends, Simon suffers a fatal allergic reaction and dies. Investigators quickly determine that his death was no accident—it was murder. Worse still, police discover that Simon planned to post major, devastating revelations about each of his four classmates the very next day, giving all of them a compelling motive. Told through alternating perspectives, the four suspects must navigate school rumors, media frenzy, and police investigations while working together to find the real killer before their secrets destroy their lives.

It offers an addictively readable, fast-paced "whodunit" thriller that masterfully combines teenage character drama with a tight, twist-filled murder mystery that keeps you guessing until the final pages.

Ideal for fans of young adult mystery thrillers, high-school drama, crime fiction puzzles, and readers looking to dive into the iconic book that launched the critically acclaimed series.
