Noughts And Crosses Malorie Blackman, 2001

The 20 years of SFX’s existence have coincided with an era when YA writers have often challenged adult assumptions about what kinds of subjects fiction for adolescents should tackle. Enter Malorie Blackman OBE, whose dystopian Noughts And Crosses sequence tackles racism and slavery. It’s also a considerable fantasy work, imagining a world where Africans gained a technological and political advantage over Europeans.
