J.K. Rowling New Book Promoted by Author In New York City Appearance: Lincoln Center Oct. 16

"Harry Potter" author J.K. Rowling is releasing a new novel on Sept. 27, and she'll appear at only one event in the U.S. to promote it — an evening with the author at New York's Jazz at Lincoln Center on Oct. 16.

Rowling's latest work is "The Casual Vacancy," an adult novel targeted at an older audience than "Harry Potter" was.

The novel, which publisher Little Brown called "blackly comic, thought-provoking and constantly surprising," will focus on the town of Pagford in the United Kingdom, the death of a parish councilman and the ensuing election to fill his seat.

"The empty seat left by Barry on the parish council soon becomes the catalyst for the biggest war the town has yet seen," Rowling's website said. "Who will triumph in an election fraught with passion, duplicity and unexpected revelations?"

When she appears at the Lincoln Center in October, Rowling will be interviewed on stage by novelist Ann Patchett and take a few audience questions. She will also sign copies of "Vacancy" for each audience member.

Though this event will be Rowling's only \U.S. appearance, she will be interviewed on several American television shows while in town, including "Nightline," "Good Morning America" and "The Daily Show With Jon Stewart."

The novel is embargoed until it's release and will not be given to media for advance reviews. But one person who has read it, Rowling's American publisher Michael Pietsch, said it solidifies Rowling as "a genius, one of the great writers of all time."

"I expect the world to be ecstatic at the range of her imaginative reach," Pietsch told USA Today.
