One of Us is Lying is a mystery novel about four high-school students: Bronwyn Rojas, Nate Macauley, Adelaide Prentiss, and Cooper Clay. They each just want to graduate high school without problems, but that’s not possible. One day, the four of them along with another student, Simon Kelleher, get stuck in detention. That same day, Simon dies from poisoning in his drink, and the police suspect it’s one of the four who killed him, especially after news comes out that Simon had dirt on each and every one of them.
