Gravel heart (Bloomsbury Publishing)

Moving from revolutionary Zanzibar in the 1960s to restless London in the 1990s, Gravel Heart is a powerful story of exile, migration and betrayal, from the Booker Prize-shortlisted author of ParadiseSalim has always believed that his father does not want him.

Living with his parents and his adored Uncle Amir in a house full of secrets, he is a bookish child, a dreamer haunted żeby night terrors. It is the 1970s and Zanzibar is changing. Tourists arrive, the island's white sands obscuring the memory of recent conflict: longed-for independence from British colonialism swiftly followed aby bloody revolution.

When his father moves out, retreating into dishevelled introspection, Salim is confused and ashamed. His mother explains neither this nor her absences with a strange man; silence is layered on silence.

When glamorous Uncle Amir, now a senior diplomat, offers Salim an escape, the lonely teenager travels to London for college. But nothing has prepared him for the biting cold and seething crowds of this hostile city.

Struggling to find a foothold, and to understand the darkness at the heart of his family, Salim must face devastating truths about himself and those closest to him - and about love, sex and power. Evoking the immigrant experience with unsentimental precision and profound insight, Gravel Heart is a powerfully affecting story of isolation, identity, belonging and betrayal, and is Abulrazak Gurnah's most dazzling achievement.
