The writer's family was living in Egypt, in exile from Libya, when Matar's father, a prominent opponent of the Qaddafi regime, was kidnapped, taken back to Libya, and imprisoned. That was in March 1990, and it was the last time Matar saw his father. After the revolution in March 2012, Matar returned to look for his father or at least try to find out what became of him.
Hisham Nitar's semi-autobiographical debut novel In the Country of Men was short-listed for the 2006 Mann Booker Prize.
Matar was born in New York City in 1970 to Libyan parents and spent his childhood in Tripoli, Libya, and later in Cairo, Egypt. He has lived in Great Britain since 1986.
Matar's father, a critic of the Libyan regime, was arrested in 1990. Matar has been unable to find out what happened to him.
