The Casual Vacancy, which came out in September, is set in a small English town called Pagford. The book starts with the death of Parish Councillor Barry Fairbrother, which leaves an empty seat on the town’s council, and leads to the "biggest war the town has ever seen."
Rowling herself says she is pleased that the novel is coming to the small screen rather than getting a movie adaptation.
"I always felt that, if it were to be adapted, this novel was best suited to television, and I think the BBC is the perfect home," she said.
"It's a book of such richness that -- through humor, social commentary and, above all, fantastic characters -- says something insightful and entertaining about the country we live in," controller of BBC Drama Ben Stephenson said in a statement.
