One of Us Is Lying (One of Us is Lying, #1)

Five Bayview High students enter detention, but only four walk out alive. Simon Kelleher, the creator of a notorious school gossip app, suffers a fatal allergic reaction while under teacher supervision. The remaining four students—Bronwyn the overachiever, Addy the homecoming queen, Nate the drug dealer, and Cooper the baseball star—become the primary suspects in a murder investigation. Police discover that Simon had prepared unpublished posts revealing scandalous secrets about each student’s private life, providing a clear motive for silence. As the investigation intensifies, the four suspects form an unlikely alliance to find the real killer while protecting their own reputations.

Fans of young adult fiction read this mystery for the combination of high-stakes suspense and subverted character archetypes. It appeals to those who enjoy seeing classic social tropes dismantled through a criminal lens. Readers walk away with an understanding of how digital gossip impacts social hierarchies and the ways common perceptions of peers rarely match their private realities. It functions as both a puzzle for armchair detectives and a look at the pressures of suburban high school expectations.
