Ruby Jane Galbraith is empty. Her family has been torn apart and it's all her fault.
The only thing that makes sense to her is Fox - a gentle new friend who is wise, soulful and clever, yet oddly naive about the ways of the world.
He understands what she's going through and he offers her a chance to find peace.
Fox belongs to a group called the Institute of the Boundless Sublime - and Ruby can't stay away from him.
So she is also drawn into what she discovers is a terrifying, secretive community that is far from the ideal world she expected.
Can Ruby find the courage to escape? Is there any way she can save Fox too? And is there ever an escape from the far-reaching influence of the Institute of the Boundless Sublime?
A gripping YA novel about an ordinary girl who is seduced into a modern-day cult.
