Sunjeev Sahota’s novels present an unvarnished image of British Asian lives. Ours Are the Streets chronicles a suicide bomber’s radicalisation, and its Booker-shortlisted successor, The Year of the Runaways, follows illegal immigrants in Sheffield — where Sahota now lives, having been raised in Derby by Punjabi-born parents. China Room, his most autobiographical work to date, mines his adolescence in deprived 1990s Chesterfield and imagines that of his great-grandmother in rural Punjab.
