Noughts & Crosses

Noughts & Crosses is a series of young adult novels, written by Malorie Blackman, set in a world where the people with dark skin (Crosses) are dominant over the white people (Noughts). The title is a reference to the game Noughts and Crosses (tic-tac-toe).

Tropes used in Noughts & Crosses include:

Alpha Bitch: Bliss, one of Callie Roses classmates. To the point where she calls Callie's hair "Blanker hair."
Alternate History: The reason why there is so much prejudice against Noughts is because they were enslaved by people from Africa, rather than the other way round.
Beta Couple: Cara Imega/Jude, and Tobey and Callie Rose.
But Not Too White: Which is the in-universe equivalent of But Not Too Black.
Children Are Innocent
Crapsack World: If you're a Nought. Also, Britain is a rare example of dystopia/CrapsackWorld in that society functions well.
Crowning Moment of Heartwarming: At the end of Noughts And Crosses, Sephy and Callum confessing to each other that they love each other as he is hanged.
Does This Remind You of Anything?: And how. Much of the attitude against Noughts mirrors prejudice against Black people during segregation in America, and to a lesser extent attitudes towards black people in Britain until the 1960's. The Liberation Milita are realistic Well-Intentioned Extremist, and Kamal Hadley's political policy of "sending white people back where the came from," resembles some peoples ideas about immigration in (modern) Britain. There is even a reference to a KKK-esque band of Crosses who tied a Nought to the back of a car and dragged him till he died for being in a Cross only area.
