Twenty-five-year-old Nigerian teacher Chimamanda Ngozi Adichie has been chosen for the short list of this year’s £30,000 Orange award, “defeating more than a dozen highly tipped and experienced authors. Adichie is up against the Booker prizewinner Margaret Atwood’s Oryx and Crake, Gillian Slovo’s panoramic vision of communist Russia, The Ice Road, and three other novels.”
