Everett’s novel, James, which focuses on Twain's enslaved character Jim, won the $10,000 prize

Percival Everett has won the $10,000 National Book Award for fiction, one of the US’s most prestigious literary prizes, for James, his acclaimed reimagining of Mark Twain’s The Adventures of Huckleberry Finn.

The 67-year-old author was also shortlisted for this year’s Booker prize for James, which focuses on Huckleberry Finn’s enslaved character Jim. The Guardian’s Anthony Cummins called the book “gripping, painful, funny, horrifying” in his review.
