The Bestseller: the addictive and suspenseful debut thriller to keep you gripped in 2026

YOU TOLD HER YOUR DARKEST SECRETS.
NOW MILLIONS WILL READ THEM . . .

Therapist Helena Averell knows that client confidentiality is the number one unbreakable rule of her job. But the constant stories of coercive control and threat she hears from her client Belle about her dangerous husband have been wearing her down. One night over too many glasses of wine, she tells her best friend Tala everything that Belle has told her.

The problem is, Tala is a down-on-her-luck novelist who is looking for an idea for her new thriller.

Months later, Tala is excitedly telling Helena that her publisher is saying this is going to be her biggest book ever. The story is Belle's story. Not only is Helena's job on the line, but if Belle's husband is as dangerous as she says, her life is too...

Why would Tala do this to Helena? She knows what's at stake.

Your friends are meant to protect you... aren't they?
