Senior School Play. The play and novel are set in an alternate history where humans evolved while Pangaea was still intact. In this history, individuals of African descent gained a technological and organisational advantage over Europeans and society is now segregated, with the Crosses (dark-skinned ruling class) in control of the Noughts (the ‘colourless’ underclass), who were once their slaves. We are introduced to and follow the intertwining lives of Sephy (a Cross), Callum (a Nought), and their families. Callum and Sephy befriended one another as children and this relationship continues, and becomes strained, when some Noughts are allowed into Heathcroft High; a school previously only accepting Crosses. However, their friendship, and eventual romance, is frowned upon owing to the segregation inherent in their society. Slowly Callum’s and Sephy’s families start to fall apart as the tensions between the Noughts and the Crosses escalate, with the increasing involvement of the Liberation Militia, a violent Nought terrorist group.
