In an alternative world, society is divided into two classes: black Crosses and white Noughts. Seffi Hadley, the daughter of an official from the Cross class, gave birth to a child from her beloved— a boy from the lower-class Noughts named Callum. After the tragedy that happened to Callum, Seffi can’t imagine what to do next, because now her little girl is doomed to live under constant threat. Callum’s brother, Jude, wants revenge on Seffi for everything she has done. Soon Jude commits a crime, and if the court proves his guilt, he faces the worst of all—execution. Only Seffi can provide him with an alibi. But is she ready to help a person who wants to kill her?
