Sephy is a Cross: she lives a life of privilege and power. But she’s lonely, and burns with injustice at the world she sees around her.
Callum is a nought: he’s considered to be less than nothing – a blanker, there to serve Crosses – but he dreams of a better life. They’ve been friends since they were children, and they both know that’s as far as it can ever go.
Noughts and Crosses are fated to be bitter enemies – love is out of the question. Then – in spite of a world that is fiercely against them – these star-crossed lovers choose each other. But this is love story that will lead both of them into terrible danger… and which will have shocking repercussions for generations to come.
