Half of a Yellow Sun won the Women’s Prize for Fiction in 2007 and as ‘Best of the Best’ of the second decade of winners, Chimamanda Ngozi Adichie will receive a special-edition Bessie statuette, cast in manganese bronze.

The Nigerian author, who won the prize in 2007, was chosen in a public vote from a list of all 25 winners.
