Sephy is a Cross: dark-skinned and beautiful, she lives a life of privilege and power. But she burns with injustice at the world she sees around her. Callum is a nought: pale-skinned and poor, he's considered to be less than nothing. But he dreams of a better life.

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.

This new edition will feature a brand-new tie-in cover, using artwork from the BBC production.
