The Pulitzer Prize for fiction has been won by author Adam Johnson for his novel based in North Korea, 'The Orphan Master's Son'.
Last year, judges failed to select a winner of the award for fiction for the first time in 35 years. Johnson spent time in North Korea to research his book.
"I wanted to give a picture of what it was like to be an ordinary person in North Korea," said Johnson.
"It's illegal there for citizens to interact with foreigners, so the only way I could really get to know these people was through my imagination."
Tom Reiss's biography of French aristocrat Alex Dumas, 'The Black Count: Glory, Revolution, Betrayal, and the Real Count of Monte Cristo', won the Pulitzer Prize for biography.
The prize for general non-fiction was awarded to Gilbert King for 'Devil in the Grove: Thurgood Marshall, the Groveland Boys and the Dawn of a New America', which details racial injustice in Florida in 1949.
