The Group Chat Is Lying: A Psychological Thriller

Fifteen years of friendship. One forged history. And a message from a dead woman: One of you knew.

For fifteen years, five college friends have lived inside one group chat. Every miscarriage, promotion, divorce, and 2 a.m. confession — all of it typed, timestamped, saved. The chat isn't just their friendship. It's the record of their friendship.

Then Dani falls six floors from her balcony, and the police call it an accident.

At the funeral reception, four phones buzz at once. A new message. From Dani's number.

One of you knew.

As Jess, Claire, Steph, and Renata search fifteen years of history for answers, each woman finds something impossible: messages she never sent, written perfectly in her voice. Someone has been inside the archive for years — editing, deleting, planting. And every forgery orbits one night: the crash that killed the chat's sixth member, fifteen Octobers ago.

The friendship they've spent fifteen years living inside is a document.

And the document has been forged.

A propulsive psychological thriller about memory, loyalty, and the terrifying question: when the record contradicts what you remember — which one do you trust?

For readers of Liane Moriarty, Lisa Jewell, and Sally Hepworth.
