Noughts and Crosses (abridged)

Sephy is a Cross, a member of the dark-skinned ruling class. Callum is a Nought, a 'colourless' member of the underclass who were once slaves to the Crosses. The two have been friends since early childhood. But that's as far as it can go. Until the first steps are taken towards more social equality and a limited number of Noughts are allowed into Crosses schools.

A frightened girl running barefoot on a knife edge - that's how 18-year-old Sephy feels as she gazes down at her newborn daughter, Callie Rose. Whilst Sephy is a Cross, the baby's father, Callum, was a nought, giving Callie Rose dual heritage in a society where the ruling Crosses treat the pale-skinned noughts (blankers) as second-class citizens.

Sixteen years have passed since Sephy Hadley first met Callum McGregor. For Callie Rose, growing up mixed race in a world where bitter prejudice divides Noughts and Crosses has meant she's an outsider wherever she turns. Enter Jude McGregor. Jude teaches Callie about her real family history, and the more she learns the more he persuades her where her loyalties really lie. But soon Callie is caught in a trap she can't get out of - one which will have deadly consequences.

Tobey wants a better life - for him and for Callie Rose. He wants nothing to do with the violent gangs that rule the world he lives in. But when he's offered the chance to earn some extra money, how much could it hurt to just this once say yes? Callie Rose knows all about the danger of saying yes. She knows about terrible mistakes, and violence and family feuds, and the fierce divide between Noughts and Crosses. And knowing so much about the past makes her afraid for her future. Because sometimes, one little bad decision can change everything....
