On Emilia Morris's thirteenth birthday, her mother Rachel moves into a tent at the bottom of their garden. From that day on, she never says another word. Inspired by her vow of silence, other women join her and together they build the Community. Eight years later, Rachel and thousands of her followers around the world burn themselves to death.
In the aftermath of what comes to be known as the Event, the Community's global influence quickly grows. As a result, the whole world has an opinion about Rachel - whether they see her as a callous monster or a heroic martyr - but Emilia has never voiced hers publicly. Until now.
When she publishes her own account of her mother's life in a memoir called The Silence Project, Emilia also decides to reveal just how sinister the Community has become. In the process, she steps out of Rachel's shadow once and for all, so that her own voice may finally be heard.
