Half of a Yellow Sun
Half of a Yellow Sun won the 2007 Orange Prize for Fiction in the women-only section.  The award is given annually for the best original full-length book; Adichie gained £30,000 as a reward for winning the prize. Purple Hibiscus, her first novel, made the Orange Prize shortlist in 2004, and because of the success of Half a Yellow Sun, critics have said that Adichie may have even more success in the future.
