One of Us Is Lying

One of Us Is Lying by Karen M. McManus
Five students walk into detention. Only four walk out alive. When Simon, creator of Bayview High’s notorious gossip app, dies before exposing his classmates’ darkest secrets, suspicion falls on the four teens who were with him: the brain, the jock, the criminal, and the princess. But who is telling the truth, and who has the most to lose? Twisty, addictive, and impossible to put down, this international bestseller is perfect for fans of Pretty Little Liars and Gossip Girl.
