One of Us Is Lying

Five students walk into detention. Only four walk out alive. And every one of them has something to hide.

On Monday afternoon, five students report to detention at Bayview High.

Bronwyn is the brilliant overachiever headed for an Ivy League future.

Addy is the popular homecoming princess.

Nate is the troublemaker already on probation.

Cooper is the star athlete.

And Simon is the outsider behind Bayview High’s notorious gossip app.

Before detention ends, Simon is dead.

Investigators quickly determine that his death wasn’t an accident—and the four students who were in the room with him become the prime suspects.

Making matters worse, Simon had planned to expose damaging secrets about each of them the very next day.

Suddenly Bronwyn, Addy, Nate, and Cooper all have motives.

As the investigation unfolds, secrets begin coming to light and the question becomes increasingly difficult to answer:

Which one of them is lying?
