LONDON – Marlon James became the first Jamaican winner of the prestigious Booker Prize for fiction Tuesday with a vivid, violent, exuberant and expletive-laden novel based on the attempted assassination of Bob Marley. Michael Wood, chairman of the judging panel, said “A Brief History of Seven Killings” was “the most exciting book on the list” and a novel full of the “sheer pleasure” of language. “One of the pleasures of reading it is you turn the page and you are not sure who the next narrator will be,” said Wood, a professor emeritus of English at Princeton University.
