Sephy and Callum were never supposed to be together in their worlds of violence, fear, hatred and separation. For Sephy is a Cross, and Callum is a nought - and noughts and Crosses must never fall in love. It's as simple as black and white ...But they have defied the rules. A passionate love is growing, and a powerful rebellion is beginning to stir. For generations to come, nothing will ever be the same again. Groundbreaking and explosive, Malorie Blackman's original dystopian masterpieces are collected together here for the first time.
