Things do not happen quite as he imagined - the school where he teaches is cramped and violent, he forgets how it feels to belong. But there is Emma, beautiful, rebellious Emma, who turns away from her white, middle-class roots to offer him love and bear him a child. And in return he spins stories of his home and keeps her a secret from his family.

Twenty years later, when the barriers at last come down in Zanzibar, he is able and compelled to go back. What he discovers there, in a story potent with truth, will change the entire vision of his life.
